Teresina is the capital city of the Brazilian state of Piauí, located in the northeast of this South American country. Although it is located on the Atlantic Ocean, it has the shortest coastline of any of the states in Brazil, at only 66 kilometres in length. The total area of the state is a little over 251 529 square kilometres (or 97 116 square miles) and it has a population of approximately 3.1 million people.
Another fact for which Piauí is known is that its capital city is the only one in the northeast to be located inland, because this state was originally inhabited from the inland areas and then extended outwards towards the coast. It is bordered by Maranhão, Ceará, Pernambuco, Bahia, Tocantins and, of course, the Atlantic Ocean
