A pre-Columbian archaeological and with 40 ha the largest in northern Argentina, even before Tilcara. The ruins are mainly terraces used for agriculture, but they did produce more than what was needed by its inhabitants. Consequently, they must have been involved in some kind of trade with the neighbouring villages. Until 1593, the place was used by the collas, also called humahuacans or omaguacans. What is very profound about the place, it possess a rather complex and advanced watering system.

A giant white-and-red desert rock accessible by a 25-minute hike. There's a shrine built into the side of the rock, with stairs you can climb up for a great view of the area. To the right of the shrine are some hand and footholds you can use to get even higher on the rock. To get there, follow Salta Street east over the bridge and keep going.
Municipal building with an old clock. When it strikes noon every day a statue of San Francisco Solano slowly comes out like a cuckoo clock.
A colonial-era foundation with an altarpiece dating to the late 17th century. Despite its small size, the church is a cathedral, one of the smallest churches to serve that function. It's sometimes open for visitors to come in and look around. It has lots of side rooms full of religious items, and a gift shop.
Huge statue crowning a small rise just west of the center and reached by climbing a long flight of steps. At the top there is a nice view of the Rio Grande valley and the town center not marred by the statue. There is also an adobe belfry and several cactus plants, perhaps the most photographed site in northern Argentina.
A small military watch tower built in 1600.
