Seymour Tower

Seymour Tower is a coastal defence tower built on a rocky tidal island called L'Avarison, located 2 km (1.25 miles) east of the shoreline of Jersey. One can reach it on foot during low tide, but one must take care when walking to or from the tower as the tide comes in very quickly. Jersey Heritage now operates the tower as a holiday rental. (Facilities are minimal. There is some electricity but no running water. Guests must bring back all waste (including bagged toilet waste) for disposal on shore. Guests staying overnight must bring their own sleeping bags and must be accompanied by a registered guide.)

Design
The square-shaped stone tower stands on a wider base that incorporates an artillery platform. Records suggest that these held two 12-pounder (1797), two 24-pounder (1814), or two 32-pounder (1848) guns.

History
The tower was constructed in 1782 following the Battle of Jersey (January 6, 1781), and is one of thirty coastal towers that Conway planned to build. Only 23 towers were built, and Seymour is the only one that is square-shaped rather than round.

In film and media
The tower and surrounding area features in "The Riddle of the Tides", an episode of the BBC documentary Coast.
