Água Suja, today Romaria, began as a settlement during the War of Paraguay, when some prospectors found diamonds. The first stone was discovered in 1857 in the Agua Suja stream, a tributary of the Bagagem River. A chapel was built to honor Our Lady of Abadia and an image was brought from Portugal. By 1926 there were already around fifty thousand pilgrims (romeiros) coming to worship the statue of the Virgin and the construction of a sanctuary was begun. The celebration takes place from August 6 to 15 and it attracts thousands of pilgrims who fill the small town.
