Holy Week (Semana Santa) has its most elaborate and dramtic celebrations in Andalucia. You'll find memorable processions of floats and penitents at Sevilla, Malaga, Granada and Cordoba and to a lesser extent in smaller towns such as Jerez, Arcos, Baeza and Ubeda. All culminate with dramatic candlelight processions at dawn on Good Friday, with Easter Day itself more of a family occasion.
Religious Virgins are hugely popular in Andalucia; they are normally handcrafted from wood and porcelain and spend 99.9 per cent of the year in glass-covered alcoves at the local church. Most are dusted down and placed on flower-decked thrones at Easter-time when they are lovingly and solemnly borne through the streets.
