Este (Paraguayan city right across the border), it is one of the most interesting and suggestive ruins among all. Trinidad was founded by the Indians coming from the mission of San Carlos, today in Argentina. Its main architects were the fathers Juan Batista Prímoli, from Milan and the Catalan José Grimau.
Not totally concluded, according to descriptions of travelers, this mission would have one of the largest and most beautiful churches of all the missions. Crossing the nave of the old church, we have an impressing view of the frieze on the top of the altar wall, entirely decorated on the rock with a sequence of angels in a barroc standing with its instruments. It is worth to mention the two access doors to the sacristy: the columns of disproportional capitals, with a triple line of leaves supporting the frieze with two side pillars and a sculptural motive in the center. One of the sacristies also shelters a small museum with local pieces (original colors) and a model of the mission. Don’t miss it.
During the excavations inside the church, interesting statues were found (with its original colors) along with some bones of missionaries that were buried there. To the west are the ruins of the tower and a long chapel. The tower, with its square base, remind of a tower fort and it is not known if it was a bell tower, a watch tower or both simultaneously. The chapel was probably used during the construction of the main church.
Declared as a World Heritage Site in 1993 by UNESCO: "In addition to their artistic interest, these missions represent the social and economic initiatives which accompanied the christianization of the Río de la Plata basin by the Society of Jesus in the 17th and 18th centuries."
