Fiesta de La Cruz is a major festival in Santa Cruz de La Palma, Breña Alta, and Breña Baja. On the night of May 2nd, practically all the roadside crosses in Santa Cruz, Breña Baja and Breña Alta will be decorated, most of them gorgeously. The people who worked on them sit close all night, usually making a party of it and setting off lots of fire-crackers. This is partly because the crosses are hung with jewellery.
