Hidalgo is bordered on the north by San Luis Potosí, on
the northwest by Querétaro, on the east by Veracruz and Puebla
and on the south by Tlaxcala and the State of Mexico.
More than 200 haciendas were built in Hidalgo in the 17th, 18th
and 19th centuries, used for a variety of activities in the region
such as mining, brandy distillery and the production of pulque,
a fermented alcoholic beverage.
Today, many of these haciendas have been renovated and converted
into hotels, restaurants and tourist centers. San Miguel Regla was
built in the 18th century by the wealthy mining mogul, Count Pedro
Romero de Terreros, and now serves as a luxury hotel. Santa Maria
Regla, also built in the 18th century, served as Count Romero's
residence and was the first hacienda dedicated to mining silver
and making brandy. Today, the hacienda is a tourist center and visitors
can explore its numerous underground tunnels.
