Plaza de las Armas

The largest plaza within the Spanish presidio of San Agustin del Tucson, founded in 1775, this area was originally used for military formations and drill. After construction of the first Pima County courthouse (1870), the name was changed to Court Plaza. Here traditional fiestas, circuses and other public events have been held since the 18th century.
