Keepers of the Light tells the story of the Gay Head Lighthouse, its long history and its more recent move back from the cliffs to keep it from falling into the sea due to erosion. The film was created by Liz Witham and Ken Wentworth and has been shown around the Island.

And now it goes national.

Keepers of the Light will premiere on WGBH 2 on Thursday, Nov. 15 at 9 p.m. and again on Nov. 17, 18 and 21. It will also appear on WGBX on Nov. 16, 17 and 18.
