Now this is venue to get guests talking, not least because they'll need to be transported on a flotilla of boats to reach it (after they've sampled the rum-tasting bar on shore in the Departure Lounge).


A former Victorian sea fort marooned off the coast of Portsmouth, this luxurious fortress can be your very own party isle. Inside the 15ft iron-clad walls, there are eight boutique-style bedrooms, the Crow's Nest up top for vows with a view, and the Officers' Mess - with its exposed brick wall and arched ceilings - for the main wedding party.

Ceremony capacity: 60; Plate cost per head: £90;
