Semana Santa refers to the week leading up to Easter each year, including Palm Sunday, Good Friday, and Easter Sunday. The celebrations that culminate in Antigua, Guatemala are described as the most extravagant in Latin America. Beginning on Palm Sunday, large wooden floats with figures of Christ with a cross and the Virgin Mary are carried from the churches through the city by followers who are dressed in purple and white robes and carry lanterns. On Good Friday, amazing carpets known as alfambras are laid throughout the streets. These carpets are made of a layer of sawdust, used to level the cobblestone streets, then covered in sawdust that has been dyed bright colors such as purple, green, blue, red, yellow, or black. This is laid down in intricate patterns along with flowers, usually bougainvillea, chrysanthemums, carnations and roses. Native plants and fruits are also used in these beautiful, original works of art. The procession walks over the carpets on their way to the church. More processions take place on Holy Saturday, these involving the Virgin Mary, carried by women dressed in black. Easter Sunday brings Mass and celebration, complete with fireworks and parties throughout the town.
