Slievethoul and Lugg


10 km south west of Tallaght just off the N81 before the village of Brittas.

Site Description

Slievethoul or Saggart Hill (396m) is on the westernmost edge of the Dublin Mountains.  From the summit there are fine views of the plains of Kildare and the rolling mountains to the east into Wicklow.  Slievethoul was formed from glacial deposits of sandstone, siltstone and shale laid down at the end of the last Ice Age.  Much of the hill has been replanted with spruce and larch.


There are five archaeological monuments in and around Slievethoul Wood, two on the summit and three on the northern edge beside Slade Valley Golf Club. On the summit is a megalithic tomb dating between c. 3500 - 3000BC.  This monument consists of a cairn, a chamber, a distinctive outer ring of monoliths and possible kerbstone on its northern side.  The other monument is a barrow or ring-barrow from the Bronze/Iron Age tradition (c. 2400 BC to AD 400).  It consists of a circular or oval raised area defined by a low internal bank surrounded by a ditch.  Another probable passage tomb and a more complex ring-barrow can also be found nearby in Lugg Wood.

How do I get there?
