The Parrish Art Museum, founded in 1898, opened the doors of its new, 34,400-square-foot Herzog & de Meuron-designed, building in November of 2012. The new Parrish includes 12,200 square feet of exhibition space—three times that of the Museum’s former home on Jobs Lane in Southampton. Seven sky-lit galleries devoted to the permanent collection showcase the story of America’s most enduring and influential artists’ colony—Eastern Long Island.

The mission of the Water Mill Museum is to preserve its historic water-powered grist mill, the other buildings at its site, its museum collection and inform the public about the history of the mill, the hamlet of Water Mill and the hamlet's cultural and natural heritage.

The museum's collection will contain items that best depict the many past uses of the water mill building, the agricultural base of the hamlet's first 300 years and the commercial, cultural and social development of the hamlet of Water Mill from 1644 to the present.

The Watermill Center is a laboratory for performance, art and inspiration, founded by American experimental theater stage director and playwright. Watermill Center provides an environment for emerging and established artists and thinkers to gather and explore new ideas together. Founded in 1992 by Robert Wilson, the Watermill Center opened in 2006 in a renovated former Western Union communication research facility.

The Watermill Center hosts an international artist-in-residency program where artists live, work and interact with the Watermill Center’s extensive collection of art and artifacts. More recently, art exhibitions and installations have been added to their programming. The Watermill Center is open year-round during artist rehearsal events, open houses and by appointment.
