Count of Arcos Palace, Colonial palace in Goiás, Brazil.

The Count of Arcos Palace stands in the City of Goiás, the former capital of Goiás state, and is built in the baroque style. It is named after Dom Marcos de Noronha, 6th Count of Arcos, the first governor of the captaincy of Goiás. The building is listed as a heritage asset by IPHAN.

The building began as the government seat of Marcos de Noronha, the first governor of Goiás, starting in 1749. Over time it evolved from an administrative center into a place reflecting different periods of Portuguese rule in Brazil.

The palace is named after Dom Marcos de Noronha, 6th Count of Arcos, the first governor of the captaincy of Goiás. It served as the seat of the state government of Goiás, and today it houses a museum presenting the history of the city of Goiás and its surrounding region, with exhibits on local art, history and culture.

The museum welcomes visitors year-round, though it closes temporarily in July when it serves as a government seat during the city anniversary celebrations. It helps to check hours if you plan to visit during that period.

The palace is named after Dom Marcos de Noronha, 6th Count of Arcos, the first governor of the captaincy of Goiás. The building later served as the seat of the state government of Goiás and now houses a museum.
