The main square covers about 14,000 m², one of the largest in South America. It has its original colonial character: stone floor, a Mudéjar-style fountain in the middle (it supplied the town's water until the 1930s) and buildings with their original architecture. The square was recognised as a National Monument together with the town in 1954.
Price: free · Tip: the square is beautiful at night, and it is the main stage of the December Festival of Lights.
