Roa island is shaped a little like a boxing glove with the thumb sticking out! It is nowadays permanently causewayed to the mainland at Rampside, the road across this causeway being called the "Roa Island Road" not unreasonably.
It has an area of about 3ha (7½ acres) and a population of c.100 making it England's 15th most populous offshore island! see Link
The island ceased to be truly insular when the causeway was completed in 1846 at the expense of the island's then owner John Abel Smith, a London banker and MP for Chichester & Midhurst.
