Church of the Sagrario, Jaén

The Church of the Sagrario is a Renaissance building with a facade featuring Corinthian columns supporting a classical entablature topped by an attic section. An elliptical dome covers the interior space, with oval windows and semicircular arches allowing natural light to enter throughout the day.

Construction began in 1764 following the Lisbon earthquake of 1755, which had damaged the surrounding area. The project emerged as part of wider rebuilding efforts that reshaped the city's religious and architectural character.

The church displays sculptures by Miguel Verdiguier showing Saint Michael, Saint Peter, and Saint Paul positioned above the entrance. These figures are among the first things visitors notice when approaching the building.

The main entrance is on Plaza de San Francisco and can be accessed through the north side of the adjacent cathedral. The square serves as a natural meeting point since both buildings sit directly next to each other.

The building features an unusual elliptical dome, a rare geometric solution in Renaissance churches of that era. This form creates an unexpected spatial experience inside that sets it apart from more conventional religious architecture.
