Castles and forts

Portsmouth has been referred to as Britain’s “most fortified city”. Its location on the south coast made Portsmouth a frontier for kings and admirals defending Britain from foreign powers - and also liable to attack, meaning that protections were needed. Though any such dangers have long since receded, our fortifications still stand to this day – and are perfect for exploring.

Whether you want to stand on the same spot that Henry VIII once did, walk along ancient fortifications, or follow the defensive chain along Portsmouth’s coast, this is the section for you.
