Completed in 1710, the church is famous for its distinctive architecture, a highlight of which is the enormous buttresses on the sides and back of the building.[2] Building of the present church was started in 1694 by Augustinian friar Father Antonio Estavillo, completed in 1710 and rededicated in 1896.[5] Several projects for the restoration of Paoay Church were sought by government and non-government organizations due to possible question on its structural integrity.[7] Conservation of the church's exteriors was begun by the National Historical Commission of the Philippines in the second quarter of 2019 and completed in June 2020.[4] The mortar used in the church includes sand and lime with sugarcane juice boiled with mango leaves, leather and rice straw.[13] Adjacent to the façade is a three-storey coral bell tower constructed separately from the church building on the right side resembling a pagoda.
