The sources of Baltic oak
Past trade in oak from the lands to the east and south of the Baltic Sea was extraordinary in that it dominated the Northern European market for specialized oak products for many centuries. Equally extraordinary is the fact that since the 1980s, when a large corpus of dendrochronological data from artworks was demonstrated to represent the material evidence for this past trade, we, until now, have not been able to pinpoint where, in this large re…
A Second Timber Circle, Trackways, and Coppicing at Holme-next-the-Sea Beach, Norfolk
Since 1998 archaeological investigations on Holme-next-the-Sea beach have recorded the waterlogged remains of two Bronze Age timber circles, timber structures, coppiced trees, metal objects, and salt- and freshwater marshes. The second timber circle (Holme II) is only the third waterlogged structure of its type to be discovered in Britain and only the second to be dated by dendrochronology. The felling of timbers used in Holme II has been dated t…
A Late Prehistoric Timber Alignment in the Waveney Valley, Suffolk
This paper describes the results of excavations and associated palaeoenvironmental analyses at Barsham Marshes, Suffolk, England. The site is a triple post alignment of oak stakes built at the edge of a palaeochannel of the River Waveney. The alignment has been traced for over 30 m but neither terminus of the site has been excavated. Dendrochronological dating of the timbers has produced a range of felling dates between 8 BC and AD 8 indicating a…
Beccles Triple Post Alignment, Beccles Marshes, Suffolk
This paper describes the results of two seasons of excavation and associated palaeoenvironmental analyses of a wetland site on Beccles Marshes, Beccles, Suffolk. The site has been identified as a triple post alignment of oak timbers (0.6–2.0 m long), over 100 m in length, and 3–4 m wide, running north-west to south-east towards the River Waveney. It was constructed in a single phase which has been dated dendrochronologically to 75 BC, although di…
Bronze Age Burnt Mounds and Early Medieval Timber Structures at Town Farm Quarry, Burlescombe, Devon
A multi-period site was exposed during topsoil stripping at Town Farm Quarry, Burlescombe, Devon, in 2005. Surviving remains included two Bronze Age burnt mounds with timber-lined troughs and pits, and a collection of well-preserved timber structures associated with a natural spring, constructed in the seventh century AD. A complete leather shoe of the same date was recovered from the fill of a hollowed tree trunk, probably used as a wellhead. A …
Interpreting Radiocarbon Dates Using Evidence from Tree Rings
Often it is not possible to date a sample of wood from the final growth ring of the tree from which it came. In these cases, an “old-wood offset” is apparent. A number of quantitative approaches for the assessment of this offset are available, dependent on the actual tree rings that have been dated. A range of examples are given, demonstrating how such radiocarbon measurements can be interpreted using additional information from archaeology and d…
The Adisham ‘Reredos’. What is It
This study attempts to record the ancient ‘reredos’ at Adisham Church, Kent, a monument that is very little known. It is an exotic survival from the pre-history of English wooden church furniture. The ambiguous assemblage too often seems to sabotage one's efforts to make sense of it, yet demands to be taken seriously. We attempt to explain what its original function was, with the help of dendrochronological and polychrome analysis, as well as a r…

The Detached Bell Tower, St Leonard's Parish Church, Yarpole, Herefordshire
This tower belongs to a group of early detached bell towers on the Herefordshire/Worcestershire border. The earliest phase has been tree-ring dated to 1195/6, indicating that this is the earliest of the group. Subsequent alterations can be dated to the fourteenth and fifteenth centuries, and it had achieved its present form by the late sixteenth or seventeenth century
A Later Bronze Age Well Complex at Swalecliffe, Kent
This paper examines the significance of seventeen later Bronze Age wells found during construction at Swalecliffe, in north-east Kent. The unusual depth of the features made for exceptional preservation of wooden structural elements, including steps and revetments, demonstrating rare evidence for woodworking and woodmanship. Extensive biological remains facilitated environmental reconstruction, and a lengthy dendrochronological sequence corrobora…

Bramcote Green, Bermondsey
An archaeological evaluation and excavation were carried out prior to a housing development in 1992, at Bramcote Green, in the London Borough of Southwark. Up to 3 m of organic rich, alluvial clay silts were deposited during the late Glacial period between about 12,000 BP and 9000 BP. A wide, shallow channel flowing south towards the Thames cut through the clay silts during the early Holocene and was filled with a series of clay and peat layers. …
A Roman Timber Building on the Southwark Waterfront, London
Rescue excavations in 1987–88 on the site of Courage's Brewery, Southwark, near the River Thames in central London, uncovered the very well-preserved remains of a timber building, dated by dendrochronology to A.D. 152–53. The building, 4.7 m wide and at least 10.4 m long, was of timber frame construction, with base plates, post-and-plank walls, a floor of sawn planks below contemporary ground level, to which there was a ramped entrance, and indic…

Reliability and Repeatability in Dendrochronological Analysis
Research into the dates of timber used for art‐historical objects has provided a large data set on which to test standard dendrochronological techniques. Some 177 sets of tree‐ring measurements, originally analysed by the late Dr J. M. Fletcher at Oxford University, have been re‐examined independently in the tree‐ring laboratories at the University of Sheffield and the Museum of London Archaeology Service. The results show a high level of agreeme…

Fragments of a 10th-Century Timber Arcade from Vintner's Place on the London Waterfront
AN ASSEMBLAGE of articulated timbers was recovered from an 11th-century waterfront where they had been reused. They had originally formed part of an arcade of a 10th-century building and exhibit as yet unparalleled features, including the use of an ogival arch. Dendrochronological dating suggests felling of the timbers between A.D. 956 and 979
