Task: Question Generation
Input (English): Also of major note in Ciudad Vieja is the Plaza de la Constitución (or Plaza Matriz). During the first decades of Uruguayan independence this square was the main hub of city life. On the square are the Cabildo—the seat of colonial government—and the Montevideo Metropolitan Cathedral. The cathedral is the burial place of Fructuoso Rivera, Juan Antonio Lavalleja and Venancio Flores. Another notable square is Plaza Zabala with the equestrian statue of Bruno Mauricio de Zabala. On its south side, Palacio Taranco, once residence of the Ortiz Taranco brothers, is now the Museum of Decorative Arts. A few blocks northwest of Plaza Zabala is the Mercado del Puerto, another major tourist destination.
