The chapel of the Hospital del Salvador was designed by one of the nuns from the Congregation of Daughters of Charity of Saint Vincent de Paul, and dates back to 1897. Chapel has a neo-Classical style, and in its architecture semicircular arches predominate. The façade and the main entrance, now closed, lead to an interior courtyard, and it is characterized by two columns and a pediment. A metal dome painted in green deserves special mention.

By the transept there are two additional accesses: one leading to inner aisles of the hospital, and another leading to a gallery bordering one of the courtyards. The first one is used to enter the chapel, where its design, comprising a nave oriented from west to east ending in an apse and a transept oriented from south to north, both of them with a barrel vault. In the transept, a dome with a small lantern is erected.

The three accesses to the temple are formed in the same way: a portal and two columns supporting the choir, and a large semicircular arched window with colored glass on the background. The apse is semicircular and has three large and long stained glass windows with semicircular arches; in its upper part, the pattern of a semicircular cavity and three windows is repeated, but on a smaller scale.

Foundations were made of somewhat smoothed stones; walls were made of brick masonry with lime mortar; floor beamwork made of Oregon pine, and wooden floor with a spike-type design.
