The Palazzi Barbaro, also known as Palazzo Barbaro, Ca' Barbaro, and Palazzo Barbaro-Curtis, are a pair of adjoining palaces, in the San Marco district of Venice. The first of the two palaces is in the Venetian Gothic style and was built in 1425 by Giovanni Bon Bono. The second structure was executed in the Baroque style and was built in 1694-1698 by Antonio Gaspari. In 1885 the older palazzo was purchased by a relative of the American painter John Singer Sargent, Daniel Sargent Curtis. Palazzo Barbaro became the hub of American life in Venice with visits from Sargent, Henry James, Whistler, Robert Browning and Claude Monet. Other members of the "Barbaro Circle" included Bernard Berenson, William Merritt Chase, Isabella Stewart Gardner, and Edith Wharton. The Isabella Stewart Gardner home (now Museum) in Boston in based on Palazzo Barbaro.
