In fact, the Village is especially remembered for being the seat of the Treaty of Alcañices that on 12 September 1297 defined the border between Portugal and the Crown of Castile, the oldest in Europe.

[5] During this time, the Marquises built a hospital for pilgrims, an alhóndiga for communal grain, a bridge, a series of fountains and several mills and promoted the creation of a Franciscan convent, which maintained that condition until its confiscation in 1848, as well as a palace within the fortress that is currently a residence for the elderly.

In Alcañices, until the expulsion of 1492, there was a Jewish quarter that was located outside the city walls, in the southwest of the Dentro la Villa neighborhood, on the sunny slope that looks towards the Fuente del Cañico.
