The Dominican Monastery of Santo Tomás was built under the patronage of Hernando Núñez de Arnalte (treasurer of the Catholic Monarchs), his wife, María Dávila, the Inquisitor Fray Tomás de Torquemada and the Catholic Monarchs.
The work began in 1482 and was completed in 1493; however, at the Catholic Monarchs' initiative, a palace was built around the eastern cloister, together with the sepulchre of Prince Juan in the church after he had died in 1497.
As a see for the Inquisition, the University of Santo Tomás was opened in the 16th century and remained in operation until the 19th century. The monastery has been attacked many times throughout its history: sacked during the French invasion, abandoned after the sale of church lands ordered by Mendizábal and destroyed by fires in 1699 and 1936.
The church front is based on a segmental arch and two buttresses that run through the arch vertically. The subtlety is broken by the existence of a huge rose window and the no less imposing coat of arms of the Catholic Monarchs. The decoration is completed with 10 sculptures by Gil de Siloé.
The interior stands out thanks to the elegance of the main nave and the ramifications of the ribs that make up the vault above the transept, marking off the area dedicated to the sepulchre of Prince Juan. The complex has three cloisters.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
