Feria de Abril (Seville, Spain)

Feria de Abril fills Seville's 450,000-square-meter fairground with over 1,000 casetas, hosting week-long sevillana dancing, fino sherry drinking, and flamenco finery. This Andalusian spectacle, rooted in 1847, draws millions of visitors over the course of the week, with single-night crowds topping 850,000. The rows of private casetas give the festival a distinctly exclusive, members-only atmosphere unlike more open street festivals. Sherry flows freely throughout the week, and the festival generates significant economic activity for Seville's tourism sector.
