The city's layout is based on Spanish colonial town planning, with wide plazas arranged in a grid arrangement. Two important monuments are the exquisite Santa Rosa de Viterbo church, renowned for its elaborate baroque style, and the magnificent aqueduct, constructed in the 18th century to supply the city with water. Grand churches and monasteries in Querétaro, such as the Templo de San Francisco and the Convent of La Cruz, exhibit the influence of European art and architecture with their elaborate facades and interior details.
