This 55,000-square-foot museum and 1.5-acre garden give visitors the chance to see more than 300 pieces of sculpture by dozens of artists. The museum's sculptures allow interaction with art in a different way: Viewers can walk around and, in some cases, through the work, viewing it from all sides. The outdoor sculpture garden is a walled-off piece of tranquility in the middle of downtown Dallas. The museum's 'til Midnight at the Nasher program allows visitors to hang around, as the name suggests, until midnight on the third Friday of every month, enjoying museum tours, activities and outdoor concerts.
