It is situated high above the Conwy valley, in the community of Bro Garmon, and commands views over Snowdonia.

The burial chamber at Capel Garmon dates from the 3rd millennium BC, and belongs to the Severn-Cotswold group.

It consists of a passage leading to a rectangular space, with circular chambers branching to the east and west.

The structure has undergone much renovation and the current entrance, originally one of the inner chambers, was made in the 19th century, when the tomb was used as a stable.

In addition to sherds of Beaker pottery found in the burial chamber, Capel Garmon was also home to a 1st-century BC iron fire dog which can now be seen at the National Museum of Wales in Cardiff.
