Castillo de la Mota
The Castillo de la Mota (English: Castle of the Butte) was a formidable fortress-turned-prison in existance during the turn of the 15th Century. It was situated in the province of Valladolid, in the kingdom of Castille, Spain, where it dominated the plateau, or butte, it was situated on. Originally constructed to defend the region from Moorish advances, a small town grew to surround the castle, which in turn envoloped the village in an outer wall.
From 1504 to 1506, following his attempted escape from the Castel Sant'Angelo, the Castillo de la Mota acted as a prison for Cesare Borgia. Cesare's location was kept a closely guarded secret between Pope Julius II and King Ferdinand I of Aragon; not even the Grand Master of the Assassin Order – Ezio Auditore da Firenze – was allowed to know of Cesare's whereabouts.
Eventually, Cesare escaped the castle with aid of Micheletto Corella and a bribed prison guard. Having had rope smuggled in for him, Cesare climbed down from his window and snuck past the main gate in his stolen guard uniform. Not long after his escape, the Assassins Ezio Auditore, Niccolò Machiavelli and then friend Leonardo da Vinci arrived at the fortress in pursuit of Micheletto, only to learn of Cesare's escape.
