On the banks of the Guadalquivir River once stood the imposing Castle of San Jorge, a medieval fortress that played a crucial role in the history of Seville. Over the centuries, this site served different purposes, most notably as the headquarters and prison of the Spanish Inquisition. Today, it stands as a powerful reminder of one of the darkest chapters in Spanish history.
The origins of the Castle of San Jorge date back to the Visigothic period, when it was built as part of Seville’s defensive system. Its strategic location on the right bank of the river made it a key point for controlling access to the city, especially after the construction of the Puente de Barcas, which connected both sides of the Guadalquivir.
In 1481, the castle underwent a dramatic transformation when it became the headquarters of the Spanish Inquisition in Seville. For nearly two centuries, it was the setting for interrogations, trials, and imprisonments carried out in the name of religious orthodoxy. This period left an indelible mark on the history of the city.
Repeated flooding of the Guadalquivir eventually caused structural deterioration, leading to the abandonment of the site in 1626. The castle was later demolished in 1800 during urban expansion, and its remains lay hidden beneath the Triana Market for many years.
Archaeological excavations in the late 20th century uncovered the remains of the castle. In 2009, the City of Seville inaugurated an interpretation center that allows visitors to explore the underground ruins and learn about both the medieval fortress and the tragic history of the Spanish Inquisition.
The Castle of San Jorge is a silent witness to the evolution of Seville, from its defensive origins to its role in one of the most controversial institutions in European history. Visiting this interpretation center is a powerful experience that invites reflection on the importance of memory, history, and understanding the past.
