Las Ventas is a famous bullring in Madrid.
Situated in the barrio of Guindalera in the district of Salamanca, it was inaugurated on June 17, 1931. It has a seating capacity of 25,000 and is regarded as the home of bullfighting in Spain and arguably in the world.
This bullring was designed by an architect called Espeliú. Its style is Mudéjar (Moorish) with pottery incrustations. The seats are situated in 10 "tendidos". The price of the seats depends upon how close they are to the "arena" and whether they are in the sun or the shade (the latter being more expensive). The bullfighting season starts in March and ends in December; bullfights are held every day during the San Isidro Fiesta, and every Sunday or holiday during the season. Bullfights start at 6 or 7pm and last for two to three hours.
