The Martello tower at Felixstowe Ferry has been transformed over the past three years from a derelict shell into a luxury home.

It is one of 40 remaining towers built along England's southern and eastern coast at the beginning of the 19th Century.

Developer Sophie Crockett, who bought the landmark five years ago, has worked with English Heritage to transform the building.

More than 100 Martello towers were built at the time of the Napoleonic wars.

They were based on the design of a fortified tower at Mortella Point on Corsica, which beat off two attacks by British forces in the 1790s before eventually being captured.
