Adjacent to Lazi Church is the Lazi Convent, which is considered the largest and oldest convent in the Philippines. Built in the 18th century, it served as the residence of the Spanish friars during the Spanish colonial period. The convent is made of coral stones and features a beautiful courtyard and garden. Today, it houses the Siquijor Heritage Museum, where visitors can learn about the history and culture of the island. The museum displays various artifacts, religious items, and photographs that provide insights into the local heritage. Exploring the Lazi Convent is like stepping back in time and experiencing the rich history of Siquijor.
