On Monday, a famous 800-year-old Belgian castle will be auctioned off by court order to the highest bidder, and it looks as if someone could snag a real bargain. The 13th century Corroy-le-Château located just south of Brussels and surrounded by a moat, was built by nobleman William of Brabant and remains one of Europe's most perfectly-preserved medieval strongholds. The current owners, descendants of Brabant's, have been fighting over the property for years and have now been ordered to sell it with a Monday deadline. The highest bid so far is for a measly $3 million, the International Herald Tribune reports, though it is probably worth ten times that much. However, if no other bidders come forward in time, the 16,000-sq.ft. fortress on 50+ acres will be sold for that amount.
