Twr Bach Lighthouse

This is a conical shaped tower and can be seen to the south east of the Twr Mawr lighthouse, and could well have been built before Twr Mawr.

Twr Bach Lighthouse is situated on a small island next to Llanddwyn Island which is joined by a small causeway. It is next to the old lifeboat station which remained in service until 1903.

The walls of Twr Bach Lighthouse are over 2 meters thick and only 5 meters in height, it has no windows and is powered by solar power and has a range of 7 nautical miles.

It is thought that this lighthouse was built in the early 1800’s as it appears on an Ordnance Survey map 1818 -1883, but not on an earlier chart of Lewis Morris dated 1800. Twr Bach Lighthouse is a Grade 2 listed building.
