Sark Lighthouse, Lighthouse at Point Robert, Sark, Channel Islands.

Sark Lighthouse is a navigation aid made of stone on the island's northeastern coast, featuring a white octagonal tower that rises above flat-roofed service rooms and cottages. The structure is operated remotely today and sends its beam across a wide distance to guide mariners.

Trinity House built the lighthouse in 1913 at Point Robert to guide vessels through the Channel Islands away from Blanchard Rock, several miles to the east. The stone tower was staffed by keepers until automation in 1994, after which monitoring moved to Trinity House's operations centre in Harwich, Essex.

Sark was a sought-after posting for lighthouse keepers: classed as a rock station, it paid well yet was less remote than others of that class. It may have been the only rock station where keepers could go to the pub when off duty.

Access is by steps descending the cliff face from the top at Point Robert; the lighthouse itself is automated and remotely monitored, so there are no keepers on site. The light shows every fifteen seconds and reaches about 20 nautical miles.

Sark was considered a "rock station", a class of lighthouse posting that paid well, yet it was less remote than others of that class. It may have been the only rock station where keepers could go to the pub when off duty. The light stands 65 metres above sea level and flashes every fifteen seconds.
