The heart of Armenia, four blocks east of the bus terminal. The plaza is open and a little austere — palms, a statue of Bolívar, benches, shoeshine stalls — and serves as the front yard for the cathedral on its western edge. On weekday mornings it fills with office workers; on Sunday afternoons families drift through after mass.
It is not architecturally remarkable, but it is the navigational anchor of the city centre. Half the things you will want to see are within a few blocks: the food market is two streets north, the Gobernación and the main shopping streets are right alongside, and the Carrera 14 pedestrian zone runs south from one corner.
