is known as Semana Santa de Sevilla. It is one of the city’s two biggest annual festivals, the other being the Feria de Abril (April Fair), which follows two weeks later. It is celebrated in the week leading up to Easter (Holy Week among Christians), and features the procession of pasos, floats of lifelike wooden sculptures of individual scenes of the events of the Passion, or images of the grieving Virgin Mary.

Most of the sculptures are of great antiquity and are considered artistic masterpieces, as well as being culturally and spiritually important to the local Catholic population.
