About Historic Downtown
The first settlements of this border city occurred in 1773, as a viceregal site that defended the missions from the attacks of indigenous people. While preserving its original architecture you must visit the Old Railway Hotel, the Old Municipal Presidency, the Zaragoza Market, the House of Culture, the PRONAF Building, as well as Telegraphs, Mail and Customs. Do not forget that it is the birthplace of nacho, because this snack was invented there.
