Spectacular art and design share the spotlight at these new additions to the culture map.

Philadelphia: Barnes Foundation
With its stunning new campus downtown, the Barnes—known for shaking up the way art is understood with its provocative arrangements of Renoirs and Matisses next to metal hinges and hooks—is helping visitors see Philly’s impressive arts scene in a new light.

Amsterdam: Stedelijk Museum
A thorough renovation and expansion shows off the Stedelijk’s singular modern and postwar art as well as its renowned design collection. A highlight: Gerrit Rietveld’s 1926 Harrenstein Bedroom, as perfectly balanced as a Mondrian painting.

Cleveland: Museum of Contemporary Art
In October, the 44-year-old MOCA Cleveland moved from a converted Sears store to a striking black-steel hexagon designed by Anglo-Persian architect Farshid Moussavi. It opens with a show by a roster of 16 international artists.

Oslo: Astrup Fearnley Museet
By night, the sail-shaped glass roof of this new complex, designed by Renzo Piano, glows like a magic lantern. By day, it illuminates a private collection of contemporary art, with works by Cai Guo-Qiang, Cindy Sherman, and Olafur Eliasson.

Rio de Janeiro: Museu de Arte do Rio de Janeiro
A centerpiece in the renewal of the once rundown historic port, MAR will occupy a Neoclassical palazzo, housing galleries showing Brazilian and international art. It opens this fall.
