Teresina in the context of "Northeast Region, Brazil"

The coastline of Brazil measures 7,491 km, making it the 16th longest national coastline in the world. The coastline touches exclusively the Atlantic Ocean. Brazil's coastline has many geographical features such as islands, reefs, bays, and its 2,095 beaches.

9 of Brazil's 26 states are landlocked, including the Federal District. The capitals of the 17 coastal states are close to the ocean, with the exceptions of Curitiba in Paraná, Porto Alegre in Rio Grande do Sul, Teresina in Piauí, Belém in Pará, and Macapá in Amapá.

Piauí (pronounced [pi.aˈwi] or [pjaˈwi] ) is one of the states of Brazil, located in the country's Northeast Region. The state has 1.6% of the Brazilian population and produces 0.7% of the Brazilian GDP.

Piauí has the shortest coastline of any coastal Brazilian state at 66 km (41 mi), and the capital, Teresina, is the only state capital in the northeast to be located inland. The reason for this is, unlike the rest of the area, Piauí was first colonised inland and slowly expanded towards the ocean, rather than the other way around. In the southeast of the state, the National Park of Serra da Capivara is a UNESCO World Heritage Site. The park has more than 400 archaeological sites and the largest concentration of rock paintings in the world, in a landscape dominated by canyons and caatinga.
