Keeps and ‘Great Towers’

Keeps in Spain however became extremely popular and remained as a striking architectural feature of castles of all types right until the end of the medieval period and beyond. Many late medieval castles in Spain had a large great tower, often with elaborate bartizans around the upper levels with a curtain wall forming a courtyard around the tower.

Gunpowder Artillery
The design and construction of Spanish medieval castles was only slightly influenced by the introduction of gunpowder weapons. This is because the effect of this technology was quite marginal until the late 15th century and the end of our period.

Canons were almost certainly used in the 14th century as siege weapons and there are references to the Muslims using gunpowder siege artillery in the capture of Huescar in 1324 and Baza in 1325. There are also strong documentary inferences to the deployment of canon by the Muslims in the siege of Alicante in 1342.
However, it was not until the late 15th century that references and stronger evidence support the development and superiority of gunpowder weapons over the conventional medieval weapons when used in parallel. The war of Granada (1481 – 1492) saw the effective use of cannon and firearms by the Christian forces against the Muslims.

The castles themselves however were really the same as they always had been with the walls, crenellated parapets, machicolations etc still providing the main defence.
