Olinda (Portuguese pronunciation), is an historic city in the Brazilian state of Pernambuco, located on the country's northeastern Atlantic Ocean coast, in Greater Recife (capital of Pernambuco State). It has a population of 389,494 people, covers 41.681 square kilometres (16.093 sq mi), and has a population of 9 inhabitants per square kilometer. It is noted as one of the best-preserved colonial cities in Brazil. Olinda features a number of major tourist attractions, such as a historic downtown area (World Heritage Site), churches, and the Carnival of Olinda, a popular street party, very similar to traditional Portuguese carnivals, with the addition of African influenced dances. Unlike in Rio de Janeiro and Salvador, in Olinda, admission to Carnival is free. All the festivities are celebrated on the streets, and there are no bleachers or roping. There are hundreds of small musical groups (sometimes featuring a single performer) in many genres.
