Of the stops on our day-long bus tour, this was the longest and, possibly, most interesting. The castle has an interesting history all around, but its recent history is almost as fascinating as the ancient bit.
It seems that the owner got into some difficulty over gambling debts and had to sell. The castle is now owned by Madame Tussaud's, of wax figure fame, which itself is owned by an entertainment conglomerate. In all fairness, there are only a handful of wax figures placed in suitably educational spots.
It is well worth the afternoon, or perhaps a full day visit. Even though it was April, it was also a school holiday week and the place was teeming with families and kids. The abundant educational exhibits and live demonstrations provided plenty of things to see and do. I highly recommend a visit.
