Crownhill

Crownhill is an area of northern Plymouth, in the county of Devon, England. It was originally known as Knackersknowle, meaning "the hill of the knacker's yard". In 1860 a fort was built on a high piece of land, just to the north west of the village, on the site of a building called Crown Hill, presumably because of its dominating position overlooking all the surrounding area. The village and surrounding area eventually adopted the same name. The fort was one of many Palmerston Forts built around Plymouth under the instruction of the then Prime Minister, Lord Palmerston, as a defence for the dockyard at Devonport against the French. The construction of these forts was eventually found to be unnecessary and as such they have been called "Palmerston's Follies". Crownhill Fort has now been restored as a tourist attraction and its guns are fired more often now then they ever were in anger. For a long time Crownhill was predominantly a garrison area with Plumer Barracks and more recently Seaton Barracks, demolished finally in the late 1990s.
