The Plaza de toros de la Real Maestranza de Caballería de Sevilla is a 12,000-capacity bullring in Seville, Spain. During the annual Seville Fair in Seville, it is the site of one of the most well-known bullfighting festivals in the world. It is a part of the Real Maestranza de Caballería de Sevilla, a noble guild established for traditional cavalry training. The ring itself is considered one of the city's most enjoyable tourist attractions and is certainly one of the most visited. As a stage for bullfighting, it is considered one of the world's most challenging environments because of its history, characteristics, and viewing public, which is considered one of the most unforgiving in all of bullfighting fandom.

The Palco was built for the Infante de España, Felipe de Borbón, son of Felipe V and Isabel de Farnesio. When Carlos III prohibited bullfighting celebrations in 1786, work on the sculptures was halted, even though only one-third of the plaza had been completed at the time. The old Palco de la Diputación (earlier called the Palco de Ganaderos or Herdsmen's Box) is also from this period and is situated over the toriles gate and in front of the Palco del Príncipe. After 34 years the cover of the launching slips of half of the ring was finished, to the left and right of the Palco del Príncipe; being easily viewed from the cathedral and the Giralda it was reflected in a great number of stamps of the time.
