One of the most popular festivities in Seville. It fills the city with music, food, dancing and entertainment. People dress in typical Andalusian costume: the women in flamenco or gypsy dresses, and the men in traditional country garb. It begins on Monday at midnight with the 'prueba del alumbrao', when the thousands of light bulbs all over the showground are illuminated for the first time. The main archway has a height of almost 50 metres, and is different each year. Inside the showground there are numerous marquees –spaces which serve as the venue for non-stop festivities with dancing and music. Many of them are private and admission is by invitation only. The fair's information office can tell you which ones are open to everyone. By day the fair is filled with horsewomen, riders and richly festooned carriages. You can take part in this parade by hiring a horse-drawn carriage with a driver. There is also an entertainment area with attractions and stalls selling food and drink. Another key element is the bullfighting festival held in the Plaza de la Maestranza bullring.
