Parroquia de Santa Mónica, Rivas-Vaciamadrid, Modern Catholic church in Rivas-Vaciamadrid, Spain.

Parroquia de Santa Mónica is a parish church in Rivas-Vaciamadrid, built to designs by Ignacio Vicens and José Antonio Ramos of Vicens + Ramos. Its walls are clad in weathering steel, and skylights set into the facade carry daylight into the central nave. The complex also holds the priest's housing and parish rooms.

Architects Ignacio Vicens and José Antonio Ramos created several design proposals before settling on a final version using weathering steel as the primary cladding material. This choice reflected both practical constraints and a willingness to try something different for a place of worship.

The Via Crucis consists of fourteen crosses made by José Antonio Ramos, each set on the wall as a separate station. In the apse, José Manuel Ciria's mural Creation covers the surface behind the altar with abstract forms. The parish uses these works during Lenten processions and Good Friday services.

This location sits south of Madrid and is easily reached when exploring the region. The complex welcomes visitors to view both the exterior architecture and the interior worship space.

The building uses weathering steel, a material that develops a protective rust-like coating over time instead of deteriorating completely. This particular surface quality gives the church a distinctive look that shifts subtly from year to year.
