Plaza Muñoz Gamero, also known as the Plaza de Armas, is the center of town. Street names change on either side of the plaza, but street addresses fronting the plaza bear the name Muñoz Gamero. Landmarks, restaurants and lodgings fan out from here. Both Av España and Av Bulnes are main thoroughfares to the north of the city (the latter accesses the large duty-free shopping area known as the Zona Franca).
