Sanctuary of the Holy Trinity, Colonial church in Tiradentes, Brazil

The Sanctuary of the Holy Trinity is a Baroque-Rococo church with a symmetrical three-part facade. The central block has a soapstone-framed door under a depressed arch, two upper windows, and a medallion of the Lamb of God; the pediment carries a relief of a triangle in a glory. The interior has a single nave and a simple chancel retable with a rare image of the Eternal Father in papal robes.

The first chapel was approved in 1776 and finished around 1781 for the hermit Antônio José Fraga. In 1798 a larger chapel was planned to a design by Manoel Victor de Jesus, with works beginning in 1810; the main body was ready by 1822, while the sacristies and consistory came much later. It became a Diocesan Sanctuary on 17 June 1962 and is listed nationally by IPHAN.

The sanctuary keeps a room of miracles holding ex-votos left by the faithful, and eight large banners painted in 1785 hang on the nave walls, showing Doctors of the Church and scenes of the Annunciation, Nativity, Epiphany and Ascension. The chancel retable holds a rare image of the Eternal Father dressed in papal robes.

The sanctuary stands on Rua da Santíssima Trindade in Tiradentes, uphill from the historic centre. It remains an active parish church, so visits may be limited during Masses and feast days; the room of miracles with ex-votos is inside. The facade's ornamentation was never completed, and the soapstone portal and oculus are best seen in morning light.

Eight large painted banners from 1785 hang on the nave walls, showing Doctors of the Church and scenes of the Annunciation, Nativity, Epiphany and Ascension. The chancel holds a rare image of the Eternal Father dressed in papal robes, and a room keeps ex-votos left by pilgrims.
