Zócalo
Also known as the Plaza de Armas, this square has distinctive portales (colonnades) and bells that compete for your attention. The hands-down winners are the deafening chimes of the Catedral de Nuestra Senora de la Asunción, which sits on the square's southwest corner. It dates from 1721. The runners-up are the bells of the 1635 Palacio Municipal, which have a fainter but no less insistent tune. The tower originally did double duty as a lighthouse.
