Not all castles are in ruins. Some castles, like Leeds Castle in Kent, were constantly owned and maintained. Owners typically transformed these castles to their liking, getting rid of their old period features. Think of it like remodeling a home and getting rid of popcorn ceilings.
Also, organizations like the National Trust, English Heritage, and even private companies have restored some castles to their former glory.
Restored castles can be pricey to visit because admission usually includes so much more than just entrance to the castle. It’s similar to visiting an attraction. Often restored castles have beautiful, extensive gardens with hedge mazes and sometimes quirky grottoes.
In the summer, some castles even have jousting tournaments, outdoor plays, and other special events. Warwick Castle in Warwickshire, England has one of our favorite castle toys, a fireball throwing trebuchet.
Seeing both a restored castle and a castle ruin will give you completely different, but worthwhile, experiences.
