Bryn Celli Ddu is a Neolithic passage tomb on the island of Anglesey in Wales, notable for its circular mound and stone-lined passage leading to an internal burial chamber. It is one of the better-preserved prehistoric monuments on the island.

The visible monument today comprises the earthen mound and stone chamber; a surrounding layout and archaeological remains indicate multiple phases of prehistoric activity at the site. The site is managed for public access with a short approach path and interpretive signage.

Archaeological study has shown the monument dates to the Neolithic period and that it was a ritual and burial site used and modified in later prehistory. Excavations and conservation work in the 20th century revealed the internal passage and chamber that are presented today.

Bryn Celli Ddu sits on Anglesey in northwest Wales, in a rural agricultural landscape accessible by road from local villages on the island.

• Visitor facilities: The tomb is a notable example of a Neolithic passage tomb on Anglesey and is presented with an accessible visitor area and information panels.

• Time your visit for early morning or late afternoon outside the main summer‑solstice crowd; the site can be particularly busy on clear summer weekends.
• Use the small on‑site car park and follow the short designated footpath to the cairn rather than wandering across the field-this preserves the monument and keeps your visit efficient.
• Don't rush past the earthworks: take the brief interpretive panels and short loop around the mound-many visitors only see the main chamber and miss the surrounding prehistoric features and alignment information.
