Macedo de Cavaleiros (European Portuguese pronunciation: [mɐˈseðu ðɨ kɐvɐˈlɐjɾuʃ] ⓘ) is a city and municipality in northeastern Portugal, in Bragança District.

[3] In the 5th century, when the first barbarians invaded from the Pyrenees, this region, which was part of the Roman province of Gallaecia, which was administered and judicially subordinate to the religious courts and chancellery of Asturias.

[3] The Roman process of assimilation accelerated after resistance was defeated, and many of the ancient castros were destroyed or abandoned in favour of the organized settlements in the valleys.

[4] During the Inquirições (English: Inquiries or inventory) of King Afonso, in 1258, the territory of Macedo belonged to the knights Nuno Martins and Mendes Gonçalves.

At the time it was a small settlement, relatively unimportant if compared to neighbouring Nozelo, Vale Prados, Cortiços, Sezulfe and Pinhovelo, which received their forals before Macedo de Cavaleiros.

[4][5] A vast part of the municipality (24.4%) is incorporated within the Natura 2000 initiative, with particular reference to the Morais Massif, considered the "umbigo do mundo" (Portuguese: navel of the world), due to the number of rare plant species.

[4] The lake created by the construction of the dam provided conditions for nautical sports, in addition to the creation of two beaches, and later, support facilities for golf, pedestrian trails and bike paths.

The climatic conditions in the region, and the fertility of its soils has allowed the cultivation and production of wine, cereals, olive and chestnut oils, in addition to the raising of cattle, sheep and goats in many of its fields.
