Machico, Madeira of Santana and west-southwest of Porto Santo in the extreme eastern portion of the island of Madeira. It is linked by road from Funchal (the regional capital), to the Santana and the villages of Ribeira Seca and Caniçal. To the existence of mountains on the western coast, it is sandwiched along the coast from the rest of the islands' settlements, while forests lie towards the interior and grasslands cover the north-eastern corner of the municipality.

Madeira over 6,000 "arrobas" (an "arroba" was equal to 11 to 12 kilograms) by 1455, using advisers from Sicily and financed by Genoese capital. (Genoa acted as an integral part of the island economy until the 17th century.) The accessibility of Madeira attracted Genoese and Flemish traders, who were keen to bypass Venetian monopolies. Sugarcane production was the primary engine of the island's economy, increasing the demand for labour. African slaves were used during portions of the island's history to cultivate sugar cane, and the proportion of imported slaves reached 10% of the total population of Madeira by the 16th century.
