Santa Catalina de Siena, Baroque church and monastery in Barrios Altos, Lima, Peru

Santa Catalina de Siena is a church and monastery run by the Dominican Mothers at the corner of Andahuaylas, Puno and Inambari streets in Barrios Altos, Lima's historic center. Fray Diego Maroto, the architect, designed and executed the work from its founding in 1624. The complex is built in the Baroque style and is listed as cultural heritage of Peru.

The monastery was founded on 10 February 1624, and the architect Fray Diego Maroto was charged with designing and carrying out the work. The complex is run by Dominican nuns at the corner of Andahuaylas, Puno and Inambari streets in Barrios Altos, in Lima's historic centre.

The complex reflects Dominican Order heritage in Lima and displays an original image of Saint Catherine of Siena brought by Rose of Lima. Visitors can still see the religious artworks and devotion connected to Dominican tradition today.

The complex occupies the corner of Andahuaylas, Puno and Inambari streets in Barrios Altos, in Lima's historic centre. The public devotion to the Señor del Santuario de Santa Catalina leaves the church in procession, and the catalino month is celebrated on 31 August at midnight, so visits on that date meet crowds.

In its early decades, the monastery housed around 300 nuns, making it one of the largest female religious communities of the colonial period. This substantial size shows how important and influential the institution was within Lima's society.
