Fort Blockhouse, Military fort in Gosport, England
Fort Blockhouse stands on the Haslar Peninsula, covering 21 hectares with direct access to Portsmouth Harbour, the Solent, and Haslar Lake.
The fort originated in 1417 as a defensive tower and transformed through centuries, serving as a battery in 1539 and later becoming a submarine base in 1905.
The Royal Navy Submarine Museum within Blockhouse 2 preserves maritime heritage and educates visitors about underwater naval operations throughout British history.
The site contains four distinct sections: Blockhouse 1 with military facilities, Blockhouse 2 with the museum, Blockhouse 3 for sailing, and Haslar Boat Yard.
The Submarine Escape Training Tank in Blockhouse 1 served as an essential facility for training naval personnel in underwater emergency procedures.
