Mel Gibson is about to go through a messy divorce, which explains why in recent weeks he's slashed nearly $10 million off the price of his vast estate in Greenwich. Originally priced at $39.5 million, the 15,800-square-foot "Elizabethan-inspired Tudor mansion" is now available for $29.75 million. The 75-acre property comes with lots of extras, including a terraced pool, tennis court, greenhouse, stable, staff houses, log cabin and stream-fed pond. The downside? Unless prospective bidders happen to be devoutly Catholic or just die-hard fans of The Da Vinci Code, they'll have to plan on spending millions more freshening up the spooky, church-like home. After the jump, a little tour of a property you would not want to wander around at night.
