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, an area included in Jersey's southeast coast Ramsar site. Acquired by Jersey Heritage in 2006, it has since been used for self-catering accommodation.
