Sandymount Strand

People, and in the past - there is no longer public vehicular access - cars, have been occasionally trapped by the incoming tide.

Built in 1804, it is one of many such circular defensive watchtowers along the coastlines of the British Isles, as part of a system of defences[3] to provide advance warning of a feared invasion by Napoleon.

The Tower was used by the Dublin United Tramways Company as an office,[4] and was also a popular cafe back in the 1960s.

[5] The Gallan Gréine marker stone is located at the end of the strand beside the Irishtown playing fields.

Carved by Cliodna Cussen and dedicated to James Joyce in 1983, a sighting stone stands 300 metres to the west and when aligned with the marker stone to the east, indicates the winter solstice with the sun rising over Killiney Hill around 21 December each year.
