Tirnony Dolmen
The Tirnony Dolmen is located off Tirnony Road about a mile north of Maghera in County Londonderry in Northern Ireland . The Tomb portal belongs to the “tripod dolmen” subgroup, as they are more common in Northern Ireland.
James Fergusson (1808–1886) coined the term “tripod dolmen” (tripod dolmen) in the 19th century. It is used on dolmens where the capstone rests on three supporting stones (e.g. Ballykeel , Legananny , Proleek ). The 5000 to 6000 year old dolmen has six upright stones, three of which are bearing. It has one curiosity: In front of the entrance there is a single 1.8 m high stone pillar that looks like a bearing stone. The chamber, which is about 2.8 m long, 1.4 m wide and 0.8 m high, may have been larger. In the past, a cairn will have at least partially covered the megalithic complex.
Flanking stones
Flank stones are occasionally found in front of the portal stones on one or both sides, which indicates a simple courtyard or an ante , as shown by some court tombs . Since Portal Tombs hardly show any traces of a cairn or hill more than other types , this part was probably cleared with the hill. Individual flank stones occur at Menlough in County Galway and the Browneshill Dolmen in County Carlow in Ireland, while at Ahaglaslin in County Cork , low stones are set in front of both sides of the portal and form a funnel-shaped entrance with further stones. A crescent-shaped settlement of low stones has been found at Ticloy , County Antrim , Northern Ireland.
After the dolmen collapsed in 2010, it was examined and restored in 2011. A 4.5 cm long flint knife was found.
Maghera is one of the places in Ireland where cross slabs were found. Nearby lies Sweat house of Tirkane. To the northeast of Maghera are the Dunglady ramparts and the Court Tomb Tamnyrankin .
