The Regina Coeli Church is a Roman Catholic parish church built in the historic center of Mexico City, on the corner of Regina and Bolivar Streets. The building is the only functioning portion of a former 16th century convent. The church is Churrigueresque in style from the 18th century and was part of the convent of Regina Coeli Conceptionist nuns. The former convent was closed during the Reform War and is generally not open to the public.
The church is still open to worship and visitors and contains several of its original gilded Churrigueresque altarpieces from the 18th century. One in particular, the Altar dedicated to the Virgin of the Fountain is an early, but developed example of the Churrigueresque style. Despite the church’s status as a national monument, it has had serious conservation problems due to deterioration since the mid 20th century.
