The name "Almansa" stems from the Arabic المنصف (al-manṣaf), "half way of the road".

Almansa is built at the foot of a white limestone crag, which is surmounted by a Moorish castle, and rises abruptly in the midst of a fertile and irrigated plain.

About 1 mile (1.6 km) south of the town centre stands an obelisk commemorating the Battle of Almansa fought there on 25 April 1707 during the War of Spanish Succession, in which a French, Spanish and Irish army under command of the duke of Berwick, a natural son of James II, routed the allied British, Portuguese and Spanish[dubious – discuss] troops.

[4] Annual reenactments of that battle have been formally listed in the Spanish cultural register.
