Alcaldía de San Juan (San Juan City Hall)

The building took nearly two centuries to finish. Construction on San Juan City Hall began in 1604 and continued in stages until 1789; the current façade facing Plaza de Armas was completed in 1840, designed by architect Pedro García and modeled on the Casa de la Panadería in Madrid's Plaza Mayor. Inside the Sala Capitular, slavery in Puerto Rico was abolished in 1873. The building still functions as the seat of municipal government — the mayor's office is upstairs, and the courtyard is open to visitors.
