Grey's Anatomy

But, the hospital used for most other exterior and a few interior shots is not in Seattle; these scenes are shot at the VA Sepulveda Ambulatory Care Center in North Hills, California, and occasional shots from an interior walkway above the lobby show dry California mountains in the distance. The exterior of Meredith Grey's house, also known as the Intern House, is real. In the show, the address of Grey's home is 613 Harper Lane, but this is not an actual address. The physical house is located at 303 W. Comstock St., on Queen Anne Hill, Seattle, Washington. Most scenes are taped at Prospect Studios in Los Feliz, just east of Hollywood, where the Grey's Anatomy set occupies six sound stages. Some outside scenes are shot at the Warren G. Magnuson Park in Seattle. Several props used are working medical equipment, including the MRI machine.
