Praça Minas Gerais: Mariana's Twin-Church Square

Praça Minas Gerais holds two baroque churches facing each other across a single cobbled square, a layout you will not find anywhere else in Brazil. The square itself costs nothing and never closes — no gate, no ticket booth, no closing hour. It sits on one of the highest plots in Mariana's historic center, roughly 470 meters from the town's core, at an altitude near 712 meters in the Iron Quadrangle hills.

Getting up there is the first small test. The streets climb, the cobbles are uneven, and comfortable shoes are not optional advice.

What You Actually See on the Square

The twin churches

Igreja de São Francisco de Assis stands on one side, Igreja de Nossa Senhora do Carmo on the other, and the pairing is what made this square Mariana's postcard. São Francisco's interior carries refined rococo carving, attributed to Manuel Francisco Lisboa — father of Aleijadinho — and the church was built by a lay brotherhood, which explains its lighter, less severe ornamentation compared with churches built by wealthier orders.

São Francisco opens Tuesday to Saturday, 9am to 4pm, and Sunday and holidays 8:30am to noon. Admission is R$10 full, R$5 half. Nossa Senhora do Carmo is free, opening Tuesday to Sunday 9am to noon and 1:30pm to 5pm. Both close on Mondays — plan around that or you will photograph facades only.

The pelourinho and the old council house

A stone column stands mid-square: the pelourinho, a colonial punishment post that is now a protected monument. Its presence turns a pretty square into a history lesson, and local heritage authorities have been drafting rules on how it may be used as a backdrop after it appeared in staged performances. My take — look at it for what it is, not as a photo prop.

The Casa da Câmara e Cadeia at Praça Minas Gerais 89 once held the council, the jail and public offices in one building. It now houses the Nos Trilhos do Tempo interpretive visit, open Monday to Friday plus weekends and holidays, 8am to noon and 1pm to 5pm, free of charge, with access allowed until 30 minutes before closing. Groups of up to five can walk in; larger groups need a booking 48 hours ahead by phone (31 3557-6202) or email.

How to Visit Without Wasting the Trip

Timing and season

April through September is the dry window, with temperatures roughly 13°C to 25°C and nights that call for a jacket. The rainy season from November to March turns the hills green but makes the soapstone cobbles slick — I have watched people slip on the descent from the square in January rain. Weekdays are quieter; weekends pull crowds from Belo Horizonte and Ouro Preto.

Allow about two hours for the square and both churches. Arrive in the morning when light hits the facades and the tour groups have not yet climbed the hill.

Getting there

Mariana sits about 112 kilometers from Belo Horizonte, just over two hours by car via the BR-040 and then the BR-356. Local buses link Mariana and Ouro Preto every 30 minutes, a 35-minute ride, and Mariana's municipal buses run fare-free — a detail that saves real money if you are moving around town. Long-distance coaches stop at the bus station on the outskirts, then it is a walk or a local bus uphill.

Guides wait near the churches and work for tips. Some are excellent; a few have been criticized for talking loudly inside the churches. If silence matters to you, do your reading beforehand and enter on your own.

Pairing it with the rest of Mariana

Below the square, the Catedral da Sé holds a German organ from 1701, played in recitals on set days — worth checking the schedule. The Mina da Passagem, the largest gold mine open to visitors, drops 120 meters by rail car and stays cold and wet inside. An electric carriage city tour departs from in front of the Cine Teatro Municipal on Rua Frei Durão at R$50 per rider, running Thursday to Sunday, and includes the square in its loop.

Bring cash. The mine and several small businesses do not take cards.

Frequently Asked Questions

No. The square is public, free and open at all hours. Only the churches charge or keep hours: São Francisco costs R$10 full and R$5 half, while Nossa Senhora do Carmo is free. Both are closed Mondays.

How long does it take to see the square and both churches?

Budget around two hours, including the interiors, the pelourinho and the Casa da Câmara e Cadeia. The square is compact, but the climb and the church visits add up.

The Nos Trilhos do Tempo visit at Praça Minas Gerais 89 is guided, free, and runs 8am to noon and 1pm to 5pm daily including holidays. Groups over five people must book 48 hours in advance.

What is the best month to go?

April to September, when rainfall drops and daytime temperatures sit between 13°C and 25°C. The stones are safer underfoot and the light on the church facades is clearer.
