One of the most colourful Easter celebrations is wrapping up across Spain and Latin America. Semana Santa is a week long religious celebration with a big feeling of carnival. It's a highlight on the Catholic calendar, not least in Guatemala, in Central America, where tourists and huge crowds turn out for parades of floats, elaborate carpet-making, and candlelit vigils in its UNESCO World Heritage city of Antigua. English teacher Chris Amoroso lives there. He has traveled the country extensively and has experienced Antigua's Semana Santa 5 times.
