A sea fort used during the filming of the BBC TV series Doctor Who has been put on the market and is expected to sell for millions of pounds.
No Man's Land Fort in the Solent near Portsmouth was built in the 1860s to fight off an invasion by France.
In October 1971, its exterior featured in an episode of Doctor Who called The Sea Devils with actor Jon Pertwee.
The fort - converted into a hotel - has hospitality suites, helipads, an indoor swimming pool, a gym and a roof garden.
It was most recently owned by Lexi Holdings but after the firm went into receivership last October, a new owner is being sought.
It was previously put on the market in 2005 for between £2m and £3m.
A spokeswoman for KPMG Restructuring said: "We are open to offers because this is a unique property."
