Tidal Mills are a medieval invention and there is a fine working example within the Environmental Education Centre of Marim (EECM).
The mill uses the tide as a source of energy for grinding cereals: the water dammed in the mill pond during high tide is allowed to flow during low tide, setting the grindstones in motion.
Tide mills in Portugal can be traced back to the 13th century and since then the technology has suffered no evolution. In the 1950s the major part of them was already abandoned due to the competition of mechanical mills - water mills and windmills undergone the same fate.
Tide mills were usually built in estuaries and coastal lagoons.
This mill, built in 1885, was one of three dozen that were active in the Ria Formosa area. It was the last one to be discontinued in 1970 and it was restored by the NPRF. Presently (it) is one of the three tide mills in the country that are still working.
These mills were built in low lying areas near the sea. Dams containing swinging gates were built along shallow creeks. As the tide came in, the gates swung open inwards, away from the sea. Water then filled the area behind the dam. When the tide turned, the gates swung shut, forcing the water to flow seaward through the millrace of the tidal mill. The obvious disadvantages to tidal mills is that the time of the tides shifts every day. Thus the millers had no choice but to work hours dictated by the tides. These mills seem only to have been used to grind grain. There were never very many of them compared to water mills and windmills.
Situated in the prestigious Monte Lemos area of Praia da Luz, Casa Branca and Casa Irmao are two of fourteen townhouses which are built in a crescent around a pool and set in magnificent gardens. These 2 bedroom / 1 bathroom houses are only 10 minutes walk to the beach and less than that to the restaurants and shops of Praia da Luz. These are great properties for family holidays.
