18th-century building. In the 16th century, the mills belonged to Hernán Cortés. By 1742, they were awarded to the Society of Jesus for the new missions of the Province of the Philippine Islands. After the confiscation of the Jesuit properties in 1771, the property was auctioned. After passing through various owners, it became a paper mill due to the area's natural conditions, including large waterfalls that provided immense hydraulic power. In 1910, the factory was acquired by the federal government. By 1954, it housed offices of the Ministry of Communications and Public Works (SCOP) and included a museum. Today, it is home to the Federal Police Museum.
