hit Manila leaving widespread destruction to the city, with San Agustin Church the only public building left undamaged. A series of strong earthquakes struck Manila again on 18–20 July 1880. This time, the tremors left a large crack in the east bell tower. The crack was eventually repaired, but the left tower was permanently removed with only the base remaining today. The church withstood the other major earthquakes that struck Manila before in 1645, 1699, 1754, 1796, 1825, 1852, 1863 and 1880 and served as a hospital for several of those injured during the earthquake in 1863. On 18 August 1898, the church was the site where Spanish Governor-General Fermin Jaudenes prepared the terms for the surrender of Manila to the United States of America following the Spanish–American War. On the night of 13 August 1932, a major fire inside Intramuros destroyed a portion of the adjacent San Agustin Monastery. The blaze also totally destroyed the Augustinian Provincial House across the road in Calle Real, as well as the ornate pedestrian bridge that once linked the Provincial House with the monastery. During the Japanese occupation during the Second World War, San Agustin Church became a concentration camp. The Japanese troops removed the lower portion of the right front door of the church and placed sandbags on the resulting opening, turning the entrance into a makeshift machine gun post. In the final days of the Battle of Manila, hundreds of Intramuros residents and clergy were held hostage in the church by Japanese soldiers with many hostages killed during the three-week-long battle. It was the only one among seven churches of Intramuros to survive a leveling by combined American and Filipino ground forces in May 1945. While the church sustained damage to its roof, the adjacent monastery was completely destroyed. In the 1970s the monastery was rebuilt as a museum under the design of architect Angel Nakpil. The church was renovated in 2013, with its colorful facade replaced by a sedate stone-colored one. San Agustin Church and its adjacent convent, Convento de San Agustin, served as the provincial house and headquarters of the Augustinian Province of the Most Holy Name of Jesus of the Philippines of Spain ever since the province's founding in 1575 until 1901, when it transferred to Madrid. It once again became the headquarters of the Province in 1927, during the tenure of Fr. Gaudencio Castrillo, O.S.A. until just
