Portchester Castle is a waterfront castle dating back to Norman times. The outer wall, forming a large square, was built on the ruins of an old Roman fort, and inside the wall, there's a large green space, with the castle in one corner and St. Mary's Church and yard in the opposite corner.
The overall grounds (and the green inside the outer wall) appear to be open to the public for free by English Heritage, with the castle as a fee attraction. You enter and pay through the gift shop, and I would strongly recommend the audio guide. This was one of the best audio guides I've encountered for a historical landmark. Instead of just a dry narrator, the audio guide is a dialogue between two historical inhabitants of the castle: an English soldier and a French prisoner, and they provide a great history of the castle and surrounding area in a way that is both informative and entertaining.
The audio tour will lead you first to the outer buildings of the castle, whose roofs have long since crumbled away. Finally you will enter the keep, and go up several floors in it, learning about various roles the castle has played in history - from Roman fort to Norman stronghold to military staging point in the Hundred Years' War to prison. The ground floor of the keep has some exhibits on some of the artifacts found on the grounds, and the role of archaeology, and some models of what the castle looked like at different times. If the day is not windy or wet, you can also go up on the roof of the keep and get a great view of Portsmouth across the way, using the spiral staircase in one corner of the keep. You can walk around the outer wall, along the tidelands of the bay.
The castle seems to be popular with school groups and artists seeking ruins for landscapes. There's restrooms next to the parking lot, and the gift shop has some treats and ice cream. St. Mary's Church is an active church, on the site of an Augstinian Priory from the 1100s, but you can check out the main chapel and the cemetery around it. They also have a tearoom if you are looking for a spot for sitting and tea.
Anyone going to the Portsmouth area - I'd recommend this castle! read more
