For Christie Brinkley, it’s the end of an era. The supermodel is selling her Bridgehampton, New York, estate after living there for 18 years. Known as Tower Hill, the manse was built in 1891 and showcases views that span from the Atlantic Ocean to the Connecticut shoreline. The picturesque Hamptons home has traditional exteriors, complete with a shingled façade, while the interiors are lofty and filled with light. Highlights include a double-height great room with floor-to-ceiling windows, a country-style eat-in kitchen with terrace, a gym, an office, and several reception rooms.

There are three fireplaces in the home and a spectacular 50-foot observation tower. In addition to four bedrooms in the main house, there’s also a freestanding art studio and a four-bedroom guesthouse with a greenhouse conservatory. Comprising 20 acres of rolling lawns, the property showcases a wisteria-clad pergola, stone terraces, meandering paths, a swimming pool, and a tennis court. Listed for $29.5 million, this 11,040-square-foot home has 9 bedrooms, 7 baths, and 4 half baths.
