Known for the breadth of its collection as well as the scope of its exhibitions, the Lambert—a must-see for contemporary art lovers—reopened in 2015 after a yearlong renovation that doubled its exhibition space. Housed in two elegant 17th-century mansions, this impressive assembly of contemporary artworks came out of the private collection of Paris art dealer Yvon Lambert, who founded the museum in 2000 in honor of Avignon's designation as European Capital of Culture. Comprising more than 1,200 pieces dating from the 1960s to the present, the Lambert Collection also hosts an influential series of three to four major exhibitions per year, cultural events, lectures, and arts eduction programs independently or in conjunction with other arts institutions worldwide. The foundation closes three months out of the year between new exhibitions, so be sure to check before going. The impressive bookshop carries dozens of original, limited-edition works by artists represented in the collection, including prints by Cy Twombly, Sol Lewitt, and Jenny Holzer, and the breezy courtyard café offers gourmet snacks, beverages, and light lunches under the shade of sleepy plane trees.
