João Ferro Martins

Pau dos Ferros is a Brazilian municipality in the interior of the state of Rio Grande do Norte, in the Northeast Region of Brazil. Covering an area of 260 km², it is located 389 km from Natal, the state capital. Emancipated from Portalegre in the 19th century, the name refers to a tree, likely an oiticica, which, due to its large size, provided shade and served as a resting place for cowboys who passed through the area, marking their brands with iron on the trunks of these trees, thus initiating the region's settlement.
