Castelo de Vide (European Portuguese pronunciation: [kɐʃˈtɛlu ðɨ ˈvidɨ] ⓘ) is a municipality in Portugal, with a population of 3,407 inhabitants in 2011,[1] in an area of 264.91 square kilometres (102.28 sq mi).

[2] It is unclear when humans settled Castelo de Vide, although archaeologists suggest the decision came from the morphology of the soil and from a territorial strategy to occupy and conquer land.

[4][5] The 14th-century Synagogue of Castelo de Vide in Santa Maria da Devesa still stands, and despite Portugal's expulsion of Jews in 1496 was used by Marranos as a religious sanctuary and school until the 16th century.

[3] At that time the settlement was dedicated to agriculture (cultivation of wine grapes, cotton, olives, fruits, and cereals) and raising cattle, while watermills were constructed along the ravines in Vide and Nisa.

[3] The new foral ("charter"), issued by King Manuel I in 1512 established new laws for public spaces and set the town's boundaries.
