Plaza Murillo is a central square in La Paz, Bolivia’s seat of government.
The plaza lies in the historic heart of La Paz and is surrounded by major national buildings, including the Presidential Palace, the National Congress, and La Paz Cathedral. Because it is a focal point of Bolivia’s political life, demonstrations, ceremonies, and public gatherings frequently take place there.
The square was laid out in 1558 as part of La Paz’s Spanish colonial grid. It was first called Plaza Mayor and later Plaza de Armas. In 1902, it was renamed for Pedro Domingo Murillo, an independence leader executed by Spanish forces in 1810.
The important geographic distinction is that Bolivia has Sucre as its constitutional capital, while La Paz is the country’s administrative and governmental seat. That wording makes La Paz the fair answer here. Plaza Murillo’s identity is tied to La Paz, not to Sucre or another Bolivian city.
