Adjacent to Lazi Church is the Lazi Convent, which is considered the largest convent in the Philippines. Built in the 19th century, it served as the residence of the Augustinian Recollect friars who managed the church. The convent is made of coral stones and features a beautiful courtyard and garden. Visitors can explore the various rooms and halls, which now house a museum showcasing religious artifacts and historical items. The Lazi Convent is a testament to the rich history and architectural heritage of Siquijor.
