The La Feria de abril is a week-long festival held each April in Seville, Spain that attracts millions of visitors. It began as a cattle market in the 1800s where people would set up tents to sell animals, socialize, dance, sing, eat, and drink. Today over 1,000 temporary tents known as "casetas" are erected for Sevillanos to celebrate, and it kicks off with the lighting of half a million lanterns. The festival grounds have moved over time and are now located opposite Parque de María Luisa, transforming the area into its own city for the celebration.
