HMS Varbel was a Royal Navy shore establishment during World War II, used as a base for Operation Source.
It was in the luxury 88-bedroomed Kyles Hydro Hotel at Port Bannatyne on the Isle of Bute in the Firth of Clyde off the west coast of Scotland.
The hotel was demolished in the 1970s.
The pier has gone except some old decaying piles.
