Sint-Petrus-en-Pauluskerk (Church of Saint Peter and Saint Paul), the main church of Ostend, Belgium, is a Roman Catholic Neo-Gothic church. It is built on the ashes of a previous church that occupied the site. King Leopold II enthusiastically supported a plan to build a new and more magnificent church. Construction started in 1899 and was completed and consecrated by Bishop Waffelaert on August 31, 1908. Its stained glass windows were destroyed during the two World Wars and were replaced by windows by Michiel Martens. The church is 70 meters long and 30 meters wide. Its spires are 72 meters high.
The church was built in the Neo-Gothic style according to plans by architect Louis Delacenserie, who based his design on the Gothic Cologne Cathedral and the Neo-Gothic Votivkirche in Vienna.
