Mother Church Our Lady of Belém, Cathedral in Descalvado, Brazil

Mother Church Our Lady of Belém is a cathedral in Descalvado featuring regional construction techniques and traditional Catholic church design. The building incorporates multiple architectural elements developed across different periods of its existence.

The present church was inaugurated on 6 September 1935 by Father Manoel Alves, on the site of a chapel inaugurated on 8 September 1832. That earlier chapel was built by José Ferreira da Silva to fulfil a religious vow, under the invocation of Our Lady of Belém; 8 September became the city's anniversary. The patron saint's image, carved life-size by an unknown artist, probably arrived from Europe in 1876.

The patronal image of Our Lady of Belém, carved life-size by an unknown artist and brought from Europe, probably from Italy or Spain in 1876, arrived via Bahia and Rio Claro in an ox cart driven by Estêvão, an enslaved man owned by Captain Benvindo Gonçalves Franco. The date 8 September, when the first chapel was inaugurated in 1832, became the town's anniversary.

The cathedral is easily accessible in the town center and serves as a venue for masses and religious events. Visitors should check in advance when guided tours are available, as these are offered at specific times.

The interior paintings were made by Francisco Pavlovic, a Slovenian artist who worked in inland São Paulo between 1923 and 1966. He decorated the interiors of 13 Brazilian churches, 12 of them in São Paulo state and one in Rolândia, Paraná.
