This is a list, which includes a photographic gallery, of some of the remaining historic structures and monuments in Tempe, Arizona. Tempe, known as Oidbaḍ by the Pima Native-American tribe, was also known as Hayden's Ferry during the territorial times of Arizona. It is a city in Maricopa County, Arizona Brief history The area where Tempe is currently located was once inhabited by the Hohokam between A.D. 750 and 1450. Many of the petroglyphs made by them can be seen from the trails on the south side of "A" mountain. The area, which at one time belonged to Mexico, was later inhabited by the Salt River Pima-Maricopa Indian tribes before the arrival of the European settlers from the eastern coast of the United States. In 1865, the United States established a military fort which was named Fort McDowell in what was then known as the "Arizona territory." The fort was near the Salt River and as such allowed the settlement of a small agricultural community called "Hayden's Ferry," named after a ferry service operated by Charles T. Hayden. The community's name was changed to "Tempe" after pioneer Darrell "Lord" Duppa compared the Salt River valley to the Vale of Tempe near Mount Olympus in Greece. In 1885, the 13th Arizona Territorial Legislature chose Tempe for the site of the Territorial Normal School, which became Arizona Normal School, Arizona State Teachers College, Arizona State College and finally Arizona State University. In 1887, the Phoenix Railroad was built and crossed the Salt River at Tempe, linking the town to the rest of the nation. The city was incorporated in 1894. The city has 45 listings on the National Register of Historic Places, which includes three historic neighborhood districts. Additionally, a number of properties not on the national register which are of historical interest to the city and which are included in the Tempe Historic Property Survey are also listed here. One of the main criteria of the National Register of Historic Places is that the property must be in its original location, otherwise it will be removed from the list. Two examples of properties which were listed and later dismantled to be rebuilt in another location are the Josephine Frankenberg House, which was originally located at 129 E. University Dr., and the Samuel C. Long House, which was originally located at 27 E. 6th St. Both houses are now located at 150
