This 18th-century New Spanish Baroque house belonged to councilman Tomás López de Ecala. The building has four portals on the façade, with three-centered arches resting on pillars that allow pedestrian traffic. On the ground floor, there is a fountain and the López de Ecala family crest, which were added in the last third of the 20th century. On the second floor, there is a covered gallery that leads to the main room, which has balconies overlooking the main square. Only part of the house has a third floor, where there is a viewpoint. When the city of Querétaro was declared the capital of the Republic in 1916, the Ministry of Communications was established in this building. In 1923, it became the property of the Mexican Electric Company, and in 1943, it passed to the Mexican Electric Industry of the Center. Later, it was used as the Municipal House of Culture, Municipal Library, and headquarters of the Mexican Society of Geography and Statistics. In 1979, it housed the Ministry of Tourism, and currently, it houses the state offices of Integral Family Development.
