Macapá (Brazilian Portuguese pronunciation: [makaˈpa] ⓘ) is a city in Brazil with a population of 512,902 (2020 estimate),[3] and is the capital of Amapá state in the country's North Region, located on the northern channel of the Amazon Delta near its mouth on the Atlantic Ocean.

It covers 6,407.12 square kilometres (2,473.80 sq mi) and is located northwest of the large inland island of Marajó and south of the border with French Guiana.

On February 4, 1758, Sebastião Veiga Cabral, the illegitimate child of the military governor of Trás-os-Montes, Sebastião Veiga Cabral, founded the town of São José de Macapá, under the authority of the governor of Pará, Francisco Xavier de Mendonça Furtado.

The fortress of São Joselito de Macapá was first laid out in 1764, but took 18 years to complete, due to illness among the Indian workers, and numerous escapes made by black slaves.

[6] Macapá experienced an intense hurricane in the Summer of 1811 causing extensive damage to the fortifications there but leaving much of the city intact.

[5] Macapá is connected to French Guiana by the Brazilian federal highway BR-156, which runs north of the city through the Amazonian jungle.

[9] The Oyapoque River Bridge has been open to traffic since March 20, 2017, linking Brazil and French Guiana by road for the first time.

Commercial flights connect Macapá to Belém, Brasília, Fortaleza, Recife Airport, Rio de Janeiro, Salvador, and São Paulo.

At the spring and the autumn equinox the sun rises and sets on the line of the equator and shines on the monument along the Avenue Equatorial, which runs for a mile due east of it.

The Estádio Milton Corrêa, usually known as the Zerão ("Big Zero", from its position with the midfield line exactly on the equator), is a multi-purpose stadium located in central Macapá on the R. Ilvaldo Alves Veras east of the university (UNIFAP).
