The world famous Carnival takes place at the Sambadromo (a stadium built for this event)  where the city's samba schools compete and dazzle audiences with luxurious costumes and incredible decorations. There are also more than 400 samba bands that take to the streets all over the city in processions that are followed by thousands of masked and costumed revelers. It is the great explosion of joy in Rio. A party uniting emotions, creativity, plasticity, colors, sounds and much fantasy. It is the greatest popular party and the most famous week-long dance party in the world.
