Situated on the Wirral Peninsula, Fort Perch Rock was built as a coastal defence battery during the Napoleonic period to protect the Port of Liverpool. Today, in private ownership, this Grade II listed building houses a fabulous museum. Inside lies a real cornucopia of exhibits ranging from World War II aviation to naval history displays of the doomed submarine HMS/M Thetis, the Lusitania and the Titanic. Even Beatles and Elvis Presley memorabilia is on show inside this unusual fortress in the Mersey Estuary!
