Not much is known about the Miravet Templar Castle situated in the province of Catalonia,Terragona, Spain. However, most of the castles constructed in Spain for the use of the Templars were confiscated when the Templars were disbanded.
Presently, more archaeological restoration is going on, though I'm not exactly sure what else has been discovered. What we do know is that archeological data of ground and the study of the furniture show that the site was occupied of ibéro-Roman epoch in our days and reveal architectural characteristics testifying Muslims' installation of al-Andalus and kingdoms of Taifas.
In the book The Secret Castle: The Key to Good and Evil, written by Miguel Bronshud, the author mentions briefly about the Templar Knights of Miravet.
If you have any information about this site, please leave a comment below. I would love to hear some history about Miravet.
