On the longest day of the year, sunlight flows into the passageway of this Neolithic burial grounds. Bryn Celli Ddu Burial Chamber is one of Anglesey’s most famous prehistoric landmarks, Bryn Celli Ddu (the ‘Mound in the Dark Grove’ in English) is actually two sites in one. In the early Neolithic (New Stone Age) period, a henge (bank and ditch) enclosing a circle of stones was built here, to be replaced later by a chambered tomb beneath a mound measuring up to 85ft/26m in diameter. Inside, a long, narrow passage leads to an octagonal chamber 8 feet/2.4m across, where artefacts such as human bones, arrowheads, and carved stones have been found.

This forest is one of the most important red squirrel conservation areas in the UK. Before 1947 (when reforestation began) the entire area consisted mainly of shifting dunes. In the late 1970s and 1980s there were fears that water levels in the forest and adjacent forest areas would fall, causing winter floods to no longer reach the same depth and dune floodplains to dry out more quickly. In 2004 it was proposed to remove large parts of the forest. The local community and conservation groups objected and a public consultation was held in 2008 on the future management of Newborough Forest.
