La Zaidía (officially La Saïdia) owes its name to the former convent, Zaidía (also sometimes called the Real Monasterio Cisterciense, or Santa María de Gratia Dei). This Convent was built on the grounds where the palace of Andalusian King Abú Zayd stood, and now is the name and location of the current. Zaidía is the Castillian version of Saïdia (in Valencian). This is because since the 19th Century, the practice of name approvals (castellanizar) of the populations, as well as streets, monuments, churches, etc. can only be done by Royal Decree.
