Tourism and History
Silvânia has cultural attractions that are valuable for local and regional culture. Monuments from the eighteenth century, century-old houses, possible archeological and remains of the bandeirante and Black colonization are some of the attractions.
Presently Silvânia has about 14 establishments related to tourism: six hotels, five restaurants and three camping grounds.[
Unlike many cities in the state of Goiás, Silvânia has a long history, beginning in 1774 when miners coming from Santa Luzia, present-day Luziânia, found gold in the region. Soon a small settlement, called Bonfim, was established. In 1943 Bonfim was substituted by Silvânia in tribute to a local figure, Vicente Miguel da Silva.
