Luggala (Irish: Log an Lágh, meaning "hollow of the hill") is a 595 metres (1,952 feet) mountain in the Wicklow Mountains, Ireland. Its cliffs are situated above a lake, Lough Tay, and are a popular location for rock climbing. Luggala is about 45 kilometres (28 miles) southwest of Dublin. The mountain forms a part of the 25 sq kms (9.7 sq miles) Luggala Estate (also known as the Guinness Estate), which is owned by wealthy arts patron Garech Browne, a member of the Guinness family. The buildings on the estate, including the luxurious Luggala Lodge (aka "Luggala Castle"), are rented commercially year-round. The estate has been used as the location of some major films, including Zardoz, Braveheart and Excalibur, as well as the historical drama television series Vikings.
