In 1690, a group from the Argentine reduction of Santa Maria founded São Lourenço Mártir . It is located about 18km west of the turn-off to São Miguel, 9km north off the road to São Luiz Gonzaga (BR-285). The church, cemetery and school are still discernible and there is a small exhibit of findings from excavations.
The most impressive find – the grand image of São Lourenço that once graced the church – is now held at the Museu das Missões in São Miguel.
