On the far wall of the hall of Courts, you will see some paintings which are very unique, as the landscape they depict is quite different from the lands of Lleida. Although they have not been restored, they show a desert where you can still make out a camel, a distinguished white building, a crescent moon and two rifles in the upper left corner and a six-pointed star in the upper right. All these elements make it possible to attribute the paintings to the Moroccan regular troops lodged there in the 1940s, when the castle still served as military barracks.

The Moroccan regular troops were Spanish military forces created in 1911 with native Moroccan recruits, when the country was a Spanish Protectorate. Organised into tabors, or battalions, they soon became an elite corps which participated in the Spanish Civil War. Their coat of arms consisted of a crescent moon and two rifles, while the six-pointed star formed part of the Moroccan flag until the year 1956, when the Protectorate came to an end and Morocco decided to adopt a five-pointed star, in representation of the five pillars of Islam.
