Of special interest to history buffs, tiny Plaza de la Villa holds some of the city’s oldest extant buildings. The plaza has been the site of city government since medieval times, and the Casa de la Villa, the old town hall, is located here. The original medieval structure was rebuilt in Renaissance style in 1645, and modified again when Spanish baroque became the rage. Subsequent modifications, including a stained glass roof over the courtyard, continued to gild the lily. A free tour in both Spanish and English is offered at 5pm on Mondays. The highlight is Goya’s painting, La Alegoria de Madrid, which personifies the city as a woman standing next to the municipal coat of arms.
