Santa Maria della Perseveranza is a modern parish church at Via della Pisana 95, in the north part of the western suburb of La Pisana which is part of the Gianicolense suburban district.
The church was designed by Francesco Fornari, and completed in 1964. It has an unusual plan, being a hexagon stretched along the major axis, and the exterior walls are very high since the church is on a crypt. There is an external apse, trapezoidal in shape and lower than the main church. The main roof is pitched, hipped and tiled and the roof of the presbyterium also slopes to its far wall. The main entrance is in one of the short sides, approached by a side staircase which leads to a patio on part of the crypt roof.
The concrete frame of the building includes eight large pilasters increasing in width with height, one on each corner and a pair in the middle of each long side of the church. These two last pairs are each close together, and frame side entrances. As a result of the shape of these pilasters, the yellow brick infill forms trapezoidal areas of wall. The only windows are at the tops of the four large infills on the longer sides, below the large concrete beams supporting the roof.
Above the main entrance, which has a triangular floating canopy, is the coat of arms of Pope John XXIII carved on a large rectangular tablet. Below the canopy is a transom window with stained glass in an abstract pattern.
The campanile is attached to the church to the left of the far end of the nave, and is a narrow rectangular brick tower with two open rectangular concrete frames side by side at the top containing the bells.
