Jersey Marine Tower

Jersey Marine Tower is an octagonal, four-stage tower that remains as a roofless shell. It is constructed of red brick, featuring rusticated quoins made from larger yellow bricks, some of which have been replaced with stone. The tower has yellow brick dressings, with stone keys and sills around the openings. On the east and west sides, there are segmental-headed doorways on the lower stage, while the other faces feature segmental-headed windows. All openings on the lower stage have been infilled. The middle stages also include segmental-headed windows, and the upper stage has taller round-headed windows with key and impost blocks. The tower is topped with a castellated crown that projects on a moulded corbel table, made of banded red and yellow bricks, and features tall merlons with moulded copings.

The interior is currently inaccessible but still shows some plaster on the walls and the joist sockets from the former upper floors. The first floor contains a wooden chimneypiece on the north side.
