This area is crowded every night and all day on Sunday, when the municipal band plays dance music from the 1940s to the 1960s. The Plaza de Independencia or Plaza de Armas is the oldest part of the city, and is filled with Indian laurel trees, surrounded by outdoor restaurants and colonial mansions. Streets here are made of cobblestone and have names such as La Calle de Bimbo and the Callejón del Ciego. In the middle of this plaza is a fountain that honors Juan Antonio de Urrutia y Arana, who built that large aqueduct to bring water to the city. Around the plaza is the Galeria Libertad (Libertad Gallery) and the Casa de Ecala (Ecala House), which is a baronial mansion from the 18th century with large balconies and wrought ironwork. However, the best-known structure on this plaza is the Palacio de la Corregiadora. The Palacio de la Corregidora was originally called the Casas Reales y Cárceles (Royal Houses and Jails). Today it houses the government of the state of Querétaro. Its name comes from its most famous occupant, Josefa Ortiz de Domínguez, who was the wife of the mayor or corregidor of the city. Ortiz de Domínguez is a heroine of the Mexican War of Independence and the Conspiracy of 1810 that led to the start of the war which occurred here. Her final resting place is the Mausoleum of the Corregidora. The Church and ex-monastery of San Felipe Neri was built between 1786 and 1805. It was opened and blessed by Miguel Hidalgo y Costilla, who also officiated the first Mass. In 1921, this church was declared the Cathedral of Querétaro by Pope Benedict XV. The church is constructed of tezontle and has altarpieces of cantera stone. The facade shows the transition between Baroque and Neoclassical architecture, and is considered to be the last Baroque facade in the city. Inside the nave is sober, austere and completely Neoclassical. The old monastery complex now houses the Ministry of Urban Development and Public Works. It is more commonly referred to as the Palace of Conín. The Church and ex-convent of Santa Rosa de Viterbo is attributed to Alarife Ignacio Maraiano de las Casas and financed by José Velasquez de Lorea, finished in 1752.
