The Romaria a Cavalo, or pilgrimage on horseback, takes place in Estremoz every year on 8th December, which is a national holiday in Portugal celebrating the Immaculate Conception.

A delight for any horse lover, the procession of riders and their animals leaves early in the morning from the main square in Estremoz en route to Vila Viçosa via Arcos and Borba, a trek of around 19 kilometres.
