Tower Hill

Newsday reports that Christie Brinkley is looking to unload her massive, 20-acre Bridgehampton estate for $29.5 million. Known as Tower Hill for its 50-foot turret, the home was built in 1891 and was scooped up by the supermodel in 1998. Her ex-husband, architect Peter Cook, restored the home, but it's been on and off the market with no luck since 2002. It was originally listed for $25 million, but after the couple's split in 2007, Brinkley re-listed it for $30 million. The main gambrel-style house, which was built with "475 tons of local rock," has 11 bedrooms, and there's also an art studio, gym, pool, tennis court, greenhouse conservatory, four-car heated garage, and four-bedroom guesthouse.
