Archaeoastronomy Database

The Archaeoastronomy Database is a crowd-sourced compilation of investigations and observations of astronomical connections that can be objectively demonstrated at ancient sites whether intended by the builders or not.  The goal is to collect as much data as possible in a searchable and categorized format so that observations can build on one another and in aggregate might contribute to our overall knowledge of the past.  (more...)

Thornborough Henges
(Three Neolithic Henges in Yorkshire)

The enigmatic Thornborough Henges are located in North Yorkshire, England, UK, and date from the Neolithic period (over 5000 years ago).  In 2023 portions of the site were donated for management by Historic England and English Heritage and are now more publicly accessible.  The video below explores astronomical connections at the site.
