Pima County Courthouse
This pink Spanish Colonial–style building with a mosaic-tile dome is among Tucson's most beautiful historic structures. Still in use, it was built in 1927 on the site of the original single-story adobe court of 1869; a portion of the old presidio wall can be seen in the south wing of the courthouse's second floor. The first floor now houses the Tucson Visitor Center and the University of Arizona Gem and Mineral Museum. Behind the building is a lovely memorial garden honoring the 19 people who were killed or injured in the shooting attack on January 8, 2011.
