Carisbrooke Castle, Isle of Wight
One of the main tourist attractions in the Isle of Wight, Carisbrooke Castle is just to the west of Newport. It's famous as the place where King Charles I was imprisoned before he was beheaded. The castle dates from around 1100 but is very well preserved, it's still possible to walk round the ramparts, and indoors there is a small museum. There's plenty for the family to see and do, with some indoor activities.
Carisbrooke Castle offers a great family day out on the Isle of Wight. There's the chance to see the famous Carisbrooke donkeys working the water wheel, and also to dress up in chain-mail and try on a soldier's uniform. There's a small museum which explains about the history of the castle, and tells about Charles I's attempted escape from his bedroom there.
There's also plenty to do outdoors. You can walk round the ramparts which offer fantastic views in all directions, explore the bowling green which may have been used by King Charles I, and take a stroll around the Princess Beatrice's newly restored Edwardian garden.
Carisbrooke Castle is run by English Heritage. It is open throughout the year, every day from 10.00 until 17.00 in the summer. For opening hours and prices see the website at http://www.english-heritage.org.uk/daysout/properties/carisbrooke-castle/prices-and-opening-times
