The Plaza de Armas is so named because it was the place where the city's defenders assembled during emergencies.
It has a level of harmony that unites all its components and it is made in the style of the plazas of Spain, such as the ones in Mérida and Trujillo.
The buildings surrounding the square are works of Baroque architecture, with stone arches and red clay roofs.
On the perimeter of the square are houses made of white stone, which serve as headquarters for major institutions such as the Municipality, the Cathedral, the Prefecture, the Superior Court, and San Cristóbal of Huamanga University.
The San Francisco de Asís church has Greco-Roman facades with raised images.
