Providing a downtown urban oasis of art and nature in the Arts District is the impressive Nasher Sculpture Center (2001 Flora St., 214/242-5100, www.nashersculpturecenter.org, Tues.–Sun. 11 a.m.–5 p.m., $10 adults, $7 seniors, $5 students, free on first Sat. and for members and children under 5). Located directly across from the Dallas Museum of Art, the facility includes an elegant 54,000-square-foot building by architect Renzo Piano (known for designing Paris’s Georges Pompidou Center) featuring the contemporary art collection of philanthropist and collector Raymond Nasher. It’s worth making the trip to experience the stunning two-acre sculpture garden, created by landscape architect Peter Walker. The open-air environment offers a distinctive museum experience featuring inter-nationally acclaimed artwork. The Nasher Collection is considered one of the primary collections of contemporary 20th-century sculpture in the world and is comprised of hundreds of works by internationally acclaimed artists. The facility is particularly proud of the depth of perspective it provides for prominent artists such as Henri Matisse (11 sculp-tures), Pablo Picasso (7), Raymond Duchamp-Villon (7), and Joan Miró (4).
