St Catherine’s Castle (Cornish: Kastel S. Kattrin) is a small Device fort commissioned by Henry VIII. It is a two-storey building built to protect Fowey Harbour in Cornwall United Kingdom. A twin battery of 64-pounder rifled muzzle-loading guns was added on a lower terrace in the 19th century. One emplacement was modified in WWII to mount a 4.7 naval gun inside a concrete shelter but was later removed to restore the Victorian gun races.
