The beauty you see today was nearly lost forever on March six, 1862. On that cold morning, a catastrophic fire broke out, fueled by the complex wooden ceilings and architectural treasures of the palace. At the time, the Alcazar was serving as the Royal Artillery School, and the fire was a tragedy for both Spanish culture and the military. However, the late nineteenth-century restoration that followed was a labor of love, designed to return the castle to an even more romantic version of its medieval self, which is why some parts feel so remarkably preserved. For a practical tip, if you are looking for the best vantage point, the Tower of Juan the Second is a must. It is accessible via a steep, narrow spiral staircase of exactly 152 steps. While the climb can be physically demanding and is not accessible for those with mobility issues, the reward is a 360 degree view of the cathedral, the Roman aqueduct, and the dramatic silhouette of the Sierra de Guadarrama mountains.
