Among the buildings built during the Viceroyalty in the current city of Monterrey, the oldest is the Palace of Guadalupe or the Bishopric, where the Regional Museum is housed. It stands on a hill overlooking the city, on land that the City Council granted to the episcopal seat of Linares in the 18th century. It was completed in 1787 at the request of the bishop of Linares (the main religious seat before being transferred to Monterrey), the Majorcan friar Rafael José Verger, of the Franciscan order. It is made of limestone, finely carved in baroque style on the main façade, arcades and impressive dome. In the 19th and early 20th centuries it served as a fortress to face the American invasion in 1846, the French invasion of 1864 and 1866, the war between Republicans and Mexican imperialists during those same dates, the rebellions of La Noria and Tuxtepec in 1871 and 1876, and the initial stage of the Mexican Revolution (1913 and 1914).
