Inner Farne Lighthouse

Inner Farne Lighthouse

Prior Castell’s Tower is the site of the first lighthouse on Inner Farne.

The tower was originally built for Thomas Castell, Prior to Durham Cathedral, from 1494 to 1519. It was used as monks’ accommodation and later a garrison.

By 1637, the tower was derelict, and in the 1670s, Captain John Blackett was given permission to establish a beacon on top of it.

The light was replaced around 1809 by the current Inner Farne Lighthouse, and Archdeacon Charles Thorp restored the tower in the 1840s.

It was used intermittently until the National Trust acquired the island in 1925.

In 2022, the range of the white light was reduced from 10 to 8 nautical miles, and the red sector increased to 8 miles.
