The U.S.'s only city-operated archaeological site, preserving a 1500-year-old Hohokam ruin in the shadow of Phoenix Sky Harbor International Airport. This ruin is one of only two Hohokam mounds remaining in the metro Phoenix area (the other being the underdeveloped Mesa Grande ruins). The museum and site is comparable to the more famous (and more remote) Casa Grande Ruins National Monument, but the visible ruins are not as large.

Tovrea Castle is a historic structure and landmark, which is particularly visible to drivers on Arizona State Route 202. It was intended as a centerpiece for a resort, but was used as a private residence for the Tovrea family, who owned the Phoenix Stockyards which once were adjacent to the property. The rococo style building was constructed in a unique three-tier fashion which has resemblance to a traditional multilayered wedding cake. The castle is now part of the Phoenix parks system and is designated as one of the Phoenix Points of Pride. The park shows over 5,000 cacti in over 100 varieties, all maintained by volunteers of the Tovrea Carraro Society. There's only 1-2 tours on weekend mornings, so they can sell out months in advance.
