The oldest traces of human presence in the Corroios territory date from the Roman occupation and can be found in Quinta do Rouxinol. In 1385 Almada, including a part of Corroios, was donated to D. Nuno Alvares Pereira, Constable of the Kingdom, by King João I. D. Nuno used his land in Corroios to create a farm and in 1403, he built the first mill of the municipality of Seixal: the still-standing Corroios Tidal Mill, now preserved and kept as an industrial monument, but still functional. The Corroios parish was founded  in 1369, until then it was a part of the larger Almada that encompassed most of the current territories of Almada and Seixal. During the Age of Discovery, this was an important loading area of shipments to Lisbon. With the creation of the Municipality of Seixal on November 6, 1836, Corroios was extinct and merged into the Freguesia of Amora. But on April 7, 1979, after almost 150 years, the Freguesia of Corroios was restored to an independent village. On May 20, 1993, Corroios rose into a town.
