HMS Hotspur was a modified 46-gun fifth rate frigate of the Royal Navy. She was built at Pembroke Dockyard and launched on 9 October 1828. She was laid up incomplete at Plymouth in April 1829. In 1859 she was recorded as being a chapel hulk based at HMNB Devonport â possibly moored at Hamoaze. She was recorded again in 1865, at the same location, as a Roman Catholic chapel hulk. She was renamed HMS Monmouth in 1868, and sold in 1902, after the Roman Catholic Church of Our Most Holy Redeemer was opened in Keyham.
