Rivas and Farasdués are two historic villages that have been dependencies of Ejea for decades. The other six centres were built in the 1950s and 1960s in order to settle inhabitants and farmers to grow irrigation crops, following the construction of the Yesa Reservoir and Bardenas irrigation channel that brought water to these villages, among others (Sádaba, Tauste, and others).
Culture
The main local festival honours the Virgin of the Olive, the local saint. In June, there is also a medieval celebration for the patron saint, Saint John the Baptist.
Another local festival commemorates The Vote Day (January 14), an event during the Black Plague in which the townsfolk voted for the bringing of the Virgin of the Olive across the town to worship her. The plague is purported to have ended in the town that day.
