Prehistoric Monuments of Anglesey

Anglesey has a wealth of prehistoric monuments scattered across the island. Some are simple standing stones in the middle of a field, or a cluster of two or three stones, some are a pile of collapsed slabs that once formed a chamber. Others are burial chambers still standing proudly, or even ones that have been reconstructed and re-covered with a mound, to resemble what they first looked like when built. This section of the Anglesey History website describes some of these monuments.

This section, launched in January 2017, is under regular development and new monuments are often being added. Please check back regularly for new additions. The monuments are grouped by commote.

The locations of all these monuments can be seen on this Google map. At the end of this page is a list of books about Anglesey prehistoric monuments.
