{{Main|Dendroarchaeology}}
The dating of buildings with wooden structures and components is also done by dendrochronology; [[dendroarchaeology]] is the term for the application of dendrochronology in archaeology. While archaeologists can date wood and when it was felled, it may be difficult to definitively determine the age of a building or structure in which the wood was used; the wood could have been reused from an older structure, may have been felled and left for many years before use, or could have been used to replace a damaged piece of wood. The dating of building via dendrochronology thus requires knowledge of the history of building technology.<ref name="sawyer1993">{{cite book |last1=Sawyer |first1=Peter |author-link1=Peter Sawyer (historian) |url=https://books.google.com/books?id=jGJrXOjYvQgC&pg=PA6 |title=Medieval Scandinavia: from conversion to Reformation, circa 800–1500 |last2=Sawyer |first2=Birgit |author-link2=Birgit Sawyer |publisher=[[University of Minnesota Press]] |year=1993 |isbn=978-0-8166-1739-5 |series=The Nordic Series |volume=17 |page=6 |oclc=489584487 |archive-url=https://web.archive.org/web/20150518110748/https://books.google.de/books?id=jGJrXOjYvQgC&pg=PA6&source=gbs_selected_pages&cad=2 |archive-date=2015-05-18 |url-status=live}}</ref>  Many prehistoric forms of buildings used "posts" that were whole young tree trunks; where the bottom of the post has survived in the ground these can be especially useful for dating.

Examples:
* The [[Post Track]] and [[Sweet Track]], ancient [[boardwalk|timber trackways]] in the [[Somerset levels]], [[England]], have been dated to 3838 BC and 3807 BC.<ref Name="Current_Archaeology_somerset-levels">{{cite journal|last=Brunning|first=Richard|title=The Somerset Levels|pages=139–143|volume=XV (4)|issue=172 (Special issue on Wetlands)|journal=Current Archaeology|date=February 2001}}</ref>
* [[Navan Fort]] where in [[Prehistoric Ireland]] a large structure was built with more than two hundred posts. The central oak post was felled in 95 BC.<ref name=navan>{{cite book |last= Lynn |first= Chris |title= Navan Fort: Archaeology and Myth |year= 2003 |publisher= Wordwell Books |location= Spain |isbn= 978-1-869857-67-7 }}</ref> 
* The [[Fairbanks House (Dedham, Massachusetts)|Fairbanks House]] in Dedham, Massachusetts. While the house had long been claimed to have been built {{circa|1640}} (and being the oldest wood-framed house in North America), core samples of wood taken from a summer beam confirmed the wood was from an oak tree felled in 1637–8, as wood was not seasoned before use in building at that time in [[New England]]. An additional sample from another beam yielded a date of 1641, thus confirming the house had been constructed starting in 1638 and finished sometime after 1641 .<ref>{{cite web|title=A Grand House in 17th-Century New England|url=http://www.fairbankshouse.org/the_house.html|publisher=Fairbanks House Historical Site|access-date=May 27, 2012|url-status=live|archive-url=https://web.archive.org/web/20120316053504/http://www.fairbankshouse.org/the_house.html|archive-date=March 16, 2012}}</ref>
