Temple of the Templars
The Knights Templar founded this castle (incorporating a temple) in the 12th Century in the city of Tomar, Portugal.
From what I understand the Knights Templar managed to recapture Spain and Portugal from the Moors but when their power started to challenge that of the established European royal families they were booted out of France and Spain and sought refuge in Portugal. They then changed their name to the "Order of Christ". But what do I know? I walk around in a daze most of the time. I may have heard all this from a bloke in a pub.
