Vernacular Architecture Group (VAG) (2021) Dendrochronology Database [data-set]. York: Archaeology Data Service [distributor]


This database is an index of tree-ring dates for 4755 buildings (or sections of buildings) as published in Vernacular Architecture up to Volume 51 (2021). It also includes about 50 building dates obtained by high precision radiocarbon dating. Descriptions of the buildings as given in the lists are included in the database. However, these descriptions have not been edited, so any references they contain relate to the volume as printed. In particular, detailed studies of some of the buildings have been published as 'individual case studies'. These are referenced, but for further information, the relevant volume of Vernacular Architecture will need to be consulted. About 395 buildings which have been investigated for tree-ring dating, but for which no date was obtained are also listed. Dates that have been superseded by later work are also indicated.

Field Descriptions

  • When applicable, the first date listed is that of primary construction.
  • Date searches are carried out using the mid-point of the range, if a date range is given.
  • The notes field should be consulted for the significance of the additional felling dates.
  • The Volume and page references are for the entries in Vernacular Architecture. A unique identifier number has also been assigned to each entry in the database (list sequence id).
  • If no range is given for the date it is precise (complete sapwood).
  • The structure and building type fields are based on information provided in the lists (occasionally modified in the light of unpublished information), and are certainly incomplete.
  • County: counties are listed as given in the original description and include both the historic and modern counties. If searching for a particular county, make sure that all the alternatives given in the drop-down list are examined.

Vernacular Architecture Group

The Vernacular Architecture Group was formed in 1952 to further the study of lesser traditional buildings. The Group has over 600 members, including some 50 overseas members, and a number of affiliated groups and exchanging societies. Membership is open to anyone interested in vernacular architecture. Members are involved in all aspects of the recording and study of vernacular buildings including detailed local or regional surveys, studies of particular types of buildings, building materials and techniques, documentary evidence and principles of development.

Searching the Dendrochronology Database

The database can be searched on the Query Page using the following fields:

Type of date - This field contains the type of date stored - Tree-ring dates, current and superceded, radiocarbon dates and undated samples.

Date Range - Enter a beginning and end date into these fields to select all records with a felling date which lies between them. For all records after a particular date omit the 'before' date and vice versa for all records before a date.
NB. Since in the inclusion of radiocarbon dates these are not solely felling dates but search for all dates using this field.

Location - The location of the Building dated, usually including town/village and name. Enter any part of the name or town.

County - Select a county from the choices in the drop down list.

Grid Reference - Grid references can be entered to different amounts of precision. Just entering the Grid letter will return everything within that 100km square. Entering numbers in the easting and northing boxes confines the search to grid references beginning with the corresponding digits.

Type of Structure - This field contains information about the structure or make up of a building (Aisled, cruck etc)

Type of Building - This field holds information about the sort of building (Barn, house, church etc)

Period - This field contains the period the date lies within using the MIDAS standard.

Laboratory - This field contains the name of the laboratory where the dating was carried out.

Identifiers - These allow you to find an entry in the database according to volume and page number in the original publications or using the List sequence database identifier.
