Las Ventas Bullring in Madrid is one of the largest in the world. Built in stunning Neo-Mudéjar style and opened in 1931, it can hold nearly 24,000 spectators. While it's known for traditional bullfights from March to October, today it also hosts concerts, events, and cultural tours. A visit offers insight into Spain’s history, architecture, and traditions. Entrance for the guided tour is €16 — and it’s definitely worth it for anyone curious about Spanish heritage.
