Once more, it is Carnival Season in many countries around the world with a Roman Catholic heritage. Celebrations and parades are put on just prior to the observance of Lent. Over the past few weeks parades and celebrations have taken place throughout Europe, the Caribbean and South America. An estimated 730,000 foreign tourists, many fleeing snowy winter conditions in Europe and the United States, traveled to Rio de Janeiro, Brazil for this year's celebrations. Collected here are a handful of images from some of the elaborate celebrations of this Carnival season. ( 39 photos total
