Facing the square is the Catedral, a large three aisle church with clerestory, elaborate aisle niches and stained glass windows. The original church dated from around 1539 and the present building is from the mid 19th century. The Palacio Nacional is on the eastern side of the square, a French neo-classical building, now the city archive. Next to it is Edificio Otero.
Notary publics, hawkers, lottery ticket sellers, food vendors and shoeshine boys among others can be found here offering customers their services.
