Fronteira was born of a dream, literally. In the 1940s Maurício Goulart, a businessman from São Paulo, envisioned a project: create a model city in the middle of central Brazil. Today Fronteira is one of a few planned communities in the region, with wide, tree-lined avenues and with a projected urban infrastructure. In 1943 Fronteira already had a post office and a public telephone. It had a small airport for those who came to play in the casinos that were legal at that time. The calling card of the town is a 12-meter statue of a nude man popularly known as "Bernardão".
