A 1930s bungalow at the front of the Royal Armouries Museum at Fort Nelson has been spectacularly blown up after being shot at by a World War II Sexton self-propelled gun.

Fort Nelson is an iconic landmark on the South Coast, built to protect Portsmouth from the threat of French invasion in the 1860s.

It has since been turned into a museum and the explosion marked the official start of a project to revamp its facilities.
