The Haslar Gunboat Yard is a unique site designed and built for the Royal Navy’s Gunboats from 1856 onwards. The Yard includes two guardhouses (a Police Barracks and a Guardhouse) which is surrounded by a wall with two watchtowers and an entrance gate.  Research has confirmed that Colonel Greene designed the gatehouses and wall. The design and detailing are of high quality and much of the original fabric survives. The importance of these structures is recognised as a Grade II* listing and both were restored in 2023. The site is home to the Hornet Services Sailing Club and Army Sailing Association.
