In the place where the Triana Market is located today, a castle was built in the Almohad period (XIII) that would later be known as the castle of San Jorge. It may have been built on previous constructions, even Roman or Visigothic, and that it was refortified after the Muslim defeat in the battle of Las Navas de Tolosa (1212).

It had ten towers that articulated a robust fortified space with a rectangular plan. The Christians would establish the headquarters of the Inquisition in Seville there in 1480, so it is certain that it was the scene of numerous episodes of imprisonment and torture throughout its history. Some of the events that occurred there have been narrated as brilliant as the one offered by Beethoven in his opera "Fidelio", which is set in this castle.
It continued to be the seat of the Inquisition until the end of the 18th century, when it was abandoned. Already at the beginning of the 19th century it was demolished and a market was built on its site. At the end of the current market, in the part that faces Castilla street, some of the great walls that belonged to the primitive castle can still be seen today.
