Bryn Celli Ddu is one of Wales' most impressive prehistoric monuments and a remarkable example of Neolithic engineering. Originally built as a passage tomb, the site dates back over 5,000 years and was designed with careful attention to the movement of the sun.
Bryn Celli Ddu is one of Wales' most impressive prehistoric monuments and a remarkable example of Neolithic engineering. Originally built as a passage tomb, the site dates back over 5,000 years and was designed with careful attention to the movement of the sun. During the summer solstice, sunlight enters the passage and illuminates the inner chamber, showing the importance of astronomy and seasonal cycles to ancient communities. Visitors can enter the passage, explore the reconstructed mound and experience one of Britain's most atmospheric ancient sites. Combined with Anglesey's coastal scenery, beaches and campsites, Bryn Celli Ddu is a perfect heritage stop for outdoor explorers.
