It is an urban unit that shows the presence of the Society of Jesus in Cartagena. The cloister, built in the XVII Century served as residence to Saint Pedro Claver, a Jesuit Priest that dedicated his missionary work to the replevying of the XVIII Century and is one of the prominent buildings in the city. Inside and under the main altar rest the relics of Saint Pedro Claver. Behind the cloister and church, the Society's School was built, that is now restored and is the site of the Naval Museum.
