These posts aren't in any particular order but this is a castle we came across in Shropshire. It's called Hopton Castle and is conincidentally located in a village called Hopton Castle though it sits in a farmer's field and as such is entirely inacessible to the public. There was a massacre here during the Civil War - 30 or so Parliamentarians were killed after a lengthy seige and supposedly had their hands cut off and thrown in the moat. They have a website which says that English Heritage are taking it over from next year.
