Cartagena, Cádiz, Córdoba, Murcia, Málaga, Seville, Valladolid, Palencia, Jerez de la Frontera, Zamora, León or Ferrol hold elaborate processions for Holy Week. A tradition dating from medieval times that has spread to other cities in Andalusia, the ""Semana Santa en Sevilla"" is notable for featuring the procession of "pasos", lifelike wood or plaster sculptures of individual scenes of the events that happened between Jesus's arrest and his burial, or images of the Virgin Mary showing grief for the torture and killing of her son. Holy week processions in Seville include marching bands that escort the pasos.
