WELCOME to the d-day BUNKER

Based just north of the home of the Royal Navy in Portsmouth, the D-Day Bunker sits deep inside Portsdown Hill. Constructed in great secrecy, the  Bunker was used as the Underground Headquarters for Operation Neptune, the seaborne assault element of Operation Overlord also known as D-Day 6th June 1944.
