Hacienda de Santa María Regla

The Hacienda de Santa María Regla is a colonial estate built across mountainous terrain in Hidalgo, organized around stone walls, gardens, and arched structures. The complex includes old furnaces and staircases that reveal the industrial operations that once took place here.

Pedro Romero de Terreros, an influential businessman in colonial Mexico, had this estate built from 1760 to 1780 to support mining operations in the region. The complex was strategically positioned to take advantage of local ore deposits and water resources.

The chapel features baroque details and is dedicated to the Virgin of Santa María de Regla, reflecting Spanish colonial religious practices. Visitors today can see how faith and architecture shaped the property's spiritual life.

Today the hacienda operates as a hotel offering rooms, an outdoor pool, and a restaurant serving local food. Visitors should note that access involves mountain roads, and arriving during daylight hours allows for better exploration of the grounds.

The property contains an extensive network of tunnels, dungeons, and aqueducts that demonstrate colonial mining engineering and infrastructure. This underground system is a rare example of how such networks were constructed in challenging mountain terrain.
