Abstract

SILVEIRA, Ana Cláudia Oliveira. Alcântara: a medieval tide mill in the periphery of Lisbon (13^th to 18^th centuries). Cadernos do Arquivo Municipal [online]. 2017, vol.ser2, n.8, pp.55-84. ISSN 2183-3176.

Alcântara from the outset was assumed as a structuring space for the city of Lisbon, despite its relative distance from the urban centre. This settlement pole was organized around a water course whose strategic value was recognized over the centuries by providing ease of communication with areas further away from the riverside, by ensuring the irrigation of both vegetable gardens and palatine gardens, by providing the installation of saltpans and the provision of motive power for various equipments that settled there from the Middle Ages to the beginning of the 20th century. This was the case of a tidal mill documented at least since the end of the thirteenth century to the mid-eighteenth century and which is one of the oldest examples known in Portugal of this type of technology, once common in the Tagus Estuary.

Keywords : Lisboa; Alcântara; Tagus Estuary; Tide mill; Cartography.
