World-famous former model Christie Brinkley has just listed her Hamptons mansion for $29.5 million.

The Tower Hill estate is located on 20 acres in Bridgehampton and holds four bedrooms in the main house, four bedrooms in the guest home, and even has a separate barn/artist studio.

The Sports Illustrated cover star’s estate sports an impressive gated entry, a greenhouse conservatory, a heated garage, and a 50-foot observation tower with views of Connecticut and the Atlantic Ocean.

Of course, the expansive grounds are impressive, too, with a private pond, a hidden tennis court, a large heated pool with a spa, and even hills for winter sledding.

“Walking through this property is like experiencing a kaleidoscope of her creative life. The views spanning to the Atlantic ocean and the Connecticut shoreline are just breathtaking. It’s simply one of the most beautiful properties I’ve ever had the privilege of representing,” said listing broker Enzo Morabito.

Brinkley has lived in her impressive Tower Hills manse for 18 years.
