El Prado Museum

El Prado was originally a natural history museum, but was converted into a museum for Spanish art in 1819. Today, over 7000 works are on display, the majority of which date back to the 17th and 18th centuries. Its highlights include Diego Velázquez’s Las Meninas, and Francisco de Goya’s La Maja Vestida and La Maja Desnuda.

Nightlife

Few cities have the vibrant nightlife found in Madrid. The city centre is crowded with night clubs, discos, late-night restaurants, bars and pubs. It happens every day of the week so don't be surprised if you find yourself in a traffic jam at 5:00 am on a Tuesday night.
In summer time, especially at night, there are many open-air terraces in the areas of the Paseo de la Castellana and the Parque del Oeste .

Bullfights

The Plaza de Toros Monumental de Las Ventas is one of the biggest and most famous bullfighting rings in the world. It was inaugurated in 1931 and is regarded as the home of bullfighting in Spain and perhaps in the world. Bullfights are a popular event and the atmosphere is always electrifying!
The ring seats 25,000 visitors. The price depends upon how close to the "arena" you sit and whether you are in the sun or the shade (the latter is more expensive).
The bullfighting season runs from March to the end of October, every Sunday.
