ALBUFEIRA is the name originated from the Arab Al-buhera, which means castle of the sea, owing to its location along the coast, or alternately al-Buħayra, for the lagoon, in reference to the lagoon that formed in the lowlands. The Arabs constructed strong defensive structures, making the area almost impregnable, allowing this area to remain in the hands of their forces longer than other possessions in Portugal.

The development of agriculture during this period was notable, with the introduction of new techniques and plant species. The Moors used the plow and fertilizers, as well as winches for lifting the water from the wells, introducing the irrigation of fields, constructing dams and transforming uncultivated areas into gardens and orchards.
