Palacio de la Marquesa de Sonora

The Palacio de la Marquesa de Sonora is a historic palace in Madrid, originally built in 1745 for the first Marquis of Regalía. Later, the Marchioness of Sonora had the building remodeled and expanded by the architect Evaristo del Castillo, with the work completed in 1828. The facade is made of granite, red brick, and Colmenar stone. The three-story building has a lobby, a large branching staircase, and a central courtyard. It once served for a time as the seat of Spain's Ministry of Justice. Since 1995, the building has been registered as a cultural asset of interest and ranks among the city's protected monuments.
