Building techniques and materials indicate the period of building: Early homes for miners and shepherds were often made of Callitris pine logs filled in with mud wattle and daub , The lack of dense stands of timber in most of South Australia meant that builders used local stone. South Australian stone buildings last longer than those in more forested states where timber was the main building material.

The scientific dating of standing buildings
Five days after the enormous explosion in Beirut that killed more than people and left up to , homeless, Joseph Khoury and his wife Gabriela Cardozo undertook a painful pilgrimage through Gemmayzeh and Mar Mikhael, two historic neighbourhoods located close to the port. Skirting rubble, and searching among facades rendered unfamiliar by catastrophic damage, they tracked down 25 of the buildings.
At each, they left behind a postcard — a reminder of what is at stake. Amid the wreckage, they were unable to identify the final five buildings. Thousands of historic buildings have already been lost in the three decades since the civil war ended, as lax state protection allowed developers to tear them down and replace them with modern skyscrapers.
Dating buildings is important for survey reports: particularly for conservation appraisals, archaeological assessments, and for predicting age-related latent defects, such as Georgian ‘snapped-header’ walls, inter- wars ‘Regent Street Disease’, or post-war high-alumina cement concrete deterioration1. When a building is original, and typical of its period, its age can usually be judged by its external appearance alone.
Every era has its distinctive architectural styles, ranging from wavy roofs of the s, to bow-backed Georgian terraces of the s. But when a building is nondescript, atypical a folly , has been altered, extended or overclad, we need to examine its structure. Structural materials, components, and systems have varied through the ages.
Knowing their periods of use can establish the era and evolution of a building. Interiors are sometimes refitted and finishes renewed, but the structure beneath them is only changed if it becomes damaged, or if it is redeveloped behind a retained facade. Rarely, lost structure is replaced by second- hand earlier structure. Building books see below illustrate contemporary construction, though beware obsolete examples.
These books, and others, can be found in the ice or IStructE libraries, and sometimes in antiquarian bookshops. The bar-charts on the opposite page summarise the periods of popular use solid lines and the tentative use broken lines of commonplace structural components and systems.
Wonderful buildings dating from the… – Old Town
Overview: A very pretty group of old stone buildings dating from before with around m2 of living space in the tree separate buildings : a main house on three floors m2 ; a small guest house 30 m2 and an old house with stone roof 45 m2 ; small outbuildings, a secured pool 12m x 6m , all set on around m2 of well-maintained grounds in a peaceful medieval hamlet near to Beynac et Cazenac in the Perigord Noir of the Dordogne.
To the side of the Old Stone House is an old outbuilding probably a pigsty with original wood door 8 m2. Between the buildings, there is a pretty courtyard with two separate eating areas sunny and shaded and pretty gardens leading across to the enclosed pool area with stunning views over the river valleys below. The pool 12m x 6m is surrounded by a stone terrace and equipped with a remote-controlled security cover.
This book presents guidance, theory, methodologies, and case studies for analyzing tree rings to accurately date and interpret historic buildings.
This book presents guidance, theory, methodologies, and case studies for analyzing tree rings to accurately date and interpret historic buildings and landscapes. Written by two long-time practitioners in the field of dendrochronology, the research is grounded in the fieldwork data of approximately structures and landscapes. By scientifically analyzing the tree rings of historic timbers, preservationists can obtain valuable information about construction dates, interpret the evolution of landscapes and buildings over time, identify species and provenance, and gain insight into the species matrix of local forests.
Authors Darrin L. Rubino and Christopher Baas demonstrate, through full-color illustrated case studies and methodologies, how this information can be used to interpret the history of buildings and landscapes and assist preservation decision-making. Over 1, samples obtained from more than 40 buildings, including high style houses, vernacular log houses, and timber frame barns, are reported. This book will be particularly relevant for students, instructors, and professional readers interested in historic preservation, cultural landscapes, museum studies, archaeology, and dendrochronology globally.

Dating Clues in Period Houses
This paper considers how the data returned by radiocarbon analysis of wood-charcoal mortar-entrapped relict limekiln fuels MERLF relates to other evidence for the construction of medieval northern European masonry buildings. A review of previous studies highlights evidence for probable residuality in the data and reflects on how this has impacted on resultant interpretations.
A critical survey of various wood-fired mortar materials and lime-burning techniques is then presented, to highlight evidence suggesting that a broad spectrum of different limekiln fuels has been exploited in different periods and that growth, seasoning, carriage and construction times are variable. It is argued that radiocarbon analysis of MERLF fragments does not date building construction directly and the heterogeneity of the evidence demands our interpretations are informed by sample taphonomy.
A framework of Bayesian modelling approaches is then advanced and applied to three Scottish case studies with contrasting medieval MERLF assemblages.

Upon encountering a new site, the archaeologist immediately requires information about its age in order to set it in context with other sites. In research into our heritage the conservationist or architect may be able to date the general period of a building he is working with from either the situation, materials of construction, type of timber joints or other stylistic features. Almost certainly the century or portion of a century when it was built may be assigned with some certainty.
However, as more and more work is done and increasing numbers of structures with complex constructional phases are encountered, the general features may not be sufficient to give the accuracy in dating that is currently required. If research into other sources of information also fails to throw light on the building’s history, resort may be made to the various scientific methods of dating. This article outlines three of the most important methods currently used for dating buildings or, in a complex situation, the order of construction within the building.
These are: dendrochronology or ‘tree-ring’ dating , radiocarbon dating and thermoluminescence dating. Each method has a distinct role in the investigation of historic buildings. None is infallible and before embarking on an extensive dating survey, due thought must be given to what might be achieved and which methods might be the more successful.

A Fellow of the Society of Antiquaries, she has extensive experience in documentary research and historic buildings. Pam will introduce our ongoing dendrochronology tree-ring dating project. The historic buildings of Wiltshire include ancient roof structures, some of which have only recently come to light through the work of WBR. The results give a fascinating glimpse into the past including the effects of the Black Death of and the early use of Arabic numerals.

Any old town is worth exploring especially in Mombasa, with buildings dating from the 16th century, built even before the nearby Portuguese Fort Jesus late 16th century. The lanes are full of old structures with beautiful wooden balconies, probably the Swahili version of the original Portuguese design. Of particular interest is the Mandhry Mosque from , featuring Swahili architecture with a distinct minaret. Do try street food and Swahili coffee found in cafes in the area.
I’ts the old part of town, so touristic just by accident which is not meant in a negative way but I find it hard to rate since it’s just a place where people live and I don’t really see what to rate. Old Town and Fort Jesus is a place that’s good to have seen though in order to get a taste of life and architecture on the east african coast centuries ago.
The outside masonry of buildings show great variety, reflecting levels of quality and sophistication, and sometimes clues to when they were built. Main influences on change are availability of stone, advances in quarrying techniques and fashion. The earliest technique, rather crude and unselective, but continues on a small scale today. Locally the stone is often a mixture or gritstone and sandstone, whatever shape is to hand and therefore cheaper.
Random rubble walling is mostly found in humbler buildings, or at the backs and sides of houses away from public view and in workshops, outhouses and walls.
Historical timbers have been sampled from buildings at 13 sites in Willsboro, New York, on the west shore of Lake Champlain. Ring-width.
Tree-Ring Services are specialists in obtaining a precise date of construction for timber-farmed buildings in the UK. Sampling involves the taking of a number of small pencil like cores from timbers and this process normally takes around hours. Full dendrochronological analysis usually takes weeks; the final report is full colour and includes the methodology, a floor plan and photographic record of sampling locations.
Where dating is successful a certificate of dendrochronological provenance is also issued. Fast track 4-week analysis is sometimes possible at a small additional cost. Contact us at Enquiries tree-ring. It often helps to include photos of timbers with e-mail communication, if you would like an initial assessment. Please be aware though that not all timbers can be dated through tree-ring analysis, the two main requirements in the UK are: a suitable species oak, pine or yew , and timbers containing sufficient rings ideally more than 50 rings.

fractions from the same building unit consistently yield the same age, we consider it a successful dating according to Criterion II (CII). Figure 5 Examples of.
Cross-dating of bricks and mortars from historical building, through thermal TL and optically stimulated OSL luminescence have achieved good accuracy and precision. However this approach is, in many cases, not exhaustive especially for buildings with different construction phases closely temporally spaced to each other. In the case of the Convento de S. Francisco Coimbra , Portugal , the dating results were crossed with the stratigraphic study of the building, mineralogical characterization by XRD and colorimetric data of the mortar samples.
Thanks to luminescence ages, mineralogical composition and color specification, two phases of construction were identified: the first from the 17 th century and the first half of the 18 th century and the second from the second half of the 18 th century to the first half of the 19 th century. These procedures are based on the assumption that the manufacture of the bricks happened almost contemporary to, or not much earlier than, its use. To overcome this issue, studies on the possibility of dating several types of historical mortars mainly lime and mud mortars through optically stimulated techniques OSL have been developed Zacharias et al.
The possibility to use mortars to evaluate the time of construction, repair works or modifications of a structure represents an important break-through in dating historical buildings. However, the choice of granulometry extracted from inert is strongly influenced by the characteristics of the mortar and the available quantity because, in order to obtain as possible accurate and precise data, several dosimeters control and measurements must be carried out.
The evaluation of bleaching degree related to the granulometry of the extracted and measured quartz has been studied in recent years.
Fashions in stone and dating buildings
Their similarity with other buildings such as Ivry-la-Bataille castle or London Tower required determining the place of Avranches keep in this group: pioneer or imitation? Therefore, samples of brick for luminescence dating were taken from the remaining little tower. Results indicate a chronology later than assumed: second part of the 12th century and first part of 13 th century.
These dates tend to prove that north-east tower remains would correspond to a reconstruction phase and not to the original construction. The keep of Avranches is one of the case studies of this group. Archeomagnetism and thermoluminescence were performed in this study in order to date the last firing of the ceramic materials such as the bricks.
Avranches’ keep remains constitute a witness of Anglo-Norman knowledge on castle building. Their similarity with other buildings such as Ivry-la-Bataille castle.
Dating a building by inscription is a long tradition, though few name the architect in such brief form as that on the Town Hall at Blandford Forum which reads ‘Bastard, Architect, ‘. The trouble with inscriptions, useful though they are, is that you cannot be sure that they are right many have been added by later owners or that they date more than a particular feature or phase of development. The datestone has to be treated with the same critical eye as the rest of the building.
Historic buildings need historians. That might seem axiomatic, but surprisingly few of the half million or so listed buildings have ever been thoroughly investigated. The rise of a specialist role of architectural historian has gone hand-in-hand with the growth of the conservation movement over the last half-century. What do architectural historians do? How can they contribute both to an understanding of architecture of all periods and to the selection of what we should seek to conserve?
Architectural historians find out about buildings; who built them and when; what they were for; how they have been altered and take the form they do now; what people and events have been associated with them. They assemble evidence and interpret it. Dating is an essential first step.
