78 kilometres (48 miles) from the current emplacement of the city, you will find this open museum on the spot where the city was originally founded (natives attacks and floods determined its relocation by 1660).
In this place, far from the more civilized Asunción, living was evidently a constant struggle. Even so (or maybe even because of that), some very important things happened here.
The first animal marking (yerra) in the continent happened here, where the idea was coined.
Much more importantly, the first revolt against colonialism took place in old Santa Fe on the night of Corpus Christi around 1580 and is known as “Revolución de los 7 Jefes” (the revolution of 7 chiefs) 5 of which were executed.
Three are the most outstanding places within this several square kilometres museum: the main museum building that features objects related to the site, maps and explanations; the cathedral place, that was found excavating and thus exposes the bodies of people that was originally burried under its pavement (a bit creepy); and the house of Vera Muxica, one of the most prominent on the sixteenth century Santa Fe, with an audio-guided reference to the ordinary life on that time.
The whole museum is ever expanding as more original buildings and objects are found, and it said to be a good candidate to receive UNESCO funds by next year, for its unique way of telling a story of a few people struggling against natural and colonial powers.
