About this source
What it is
The Alcázar of Segovia is a medieval castle and royal fortress dating back to the 12th century. It served as a royal residence, treasury and archive for the monarchs of Castile.
Why it matters
In December 1474, when news reached Segovia that King Henry IV had died, Isabella took refuge in the Alcázar, won the support of local allies, and was enthroned there as Queen of Castile and León the next day. The fortress also held the Crown's treasury, from which funds were later drawn to finance Columbus's first voyage. It shows how control of fortresses and treasure was central to securing a monarch's power.
Look closer
- Why would controlling a fortress like this matter so much to someone claiming a throne?
- What does it mean that treasury funds from here helped finance later overseas voyages?
- How might the castle's long history before and after Isabella change how we see her brief but crucial stay there?
