It was during this period that most of the current building was constructed by the Trastámara dynasty. In 1258, parts of the Alcázar had to be rebuilt by King Alfonso X after a cave-in and the Hall of Kings was built to house Parliament soon after. However, the single largest contributor to the continuing construction of the Alcázar is King John II of Castile who built the "New Tower" (John II tower as it is known today). In 1474, the Alcázar played a major role in the rise of Queen Isabella I. On 12 December news of the King Henry IV's death in Madrid reached Segovia and Isabella immediately took refuge within the walls of the Alcázar where she received the support of Andres Cabrera and Segovia's council. She was enthroned the next day as Queen of Castile and León. The next major renovation at the Alcázar was conducted by King Philip II after his marriage to Anna of Austria. He added the sharp slate spires to reflect the castles of central Europe. In 1587, architect Francisco de Morar completed the main garden and the School of Honor areas of the castle.

Prince Charles was shown the Galley Room or "second great hall" with the heraldry of Catherine of Lancaster. In the evening there was a torchlit masque involving 32 mounted knights. Prince Charles gave the Count of Chinchón a jewel and rewarded the poet Don Juan de Torres for his verses. He left early in the morning for Santa María la Real de Nieva.

He appointed Count Félix Gazzola as the director of the artillery corps, who made the executive decision to install the academy in the Segovian fortress in the Alcazar. At its opening in 1764, the military college stood as a symbol of the city’s new age of progress in
