History
Around 1670 a ship called The Castle of Comfort, based in Southampton, was de-commissioned and broken up at nearby Portchester.
The ship was built in the early 1600's and was owned by a Privateer. It was a commercial ship sanctioned by the British Government and had spent it's life plundering treasures from South America.
A wealthy man from Medstead bought the main timbers to build a beer house, which locally became known as The Castle of Comfort.
Todays building was built on the site of the original Castle of Comfort in the early 1800's after fire destroyed the original. The old cellar still exists and probably has some of the orginal beams.
