The Marco Zero do Equador is a monument built in 1987 in Macapá's Jardim Marco Zero district to mark exactly where the equator crosses the city, and it is Macapá's best-known sight. At its centre stands a 30-metre obelisk with a circular opening at the top, and the monument marks on the ground the line between the northern and southern hemispheres. On the equinoxes, 21 or 22 March and 22 or 23 September, when day and night are equal, the sun fills the round opening at the top of the obelisk and casts its shadow on the ground, and the site holds equinox celebrations with shows, workshops and fairs; in March 2026 an Equinox Festival ran over three days. Facing the monument is the Zerão football stadium, whose halfway line lies on the equator, so each team kicks off in a different hemisphere. The site is free and open, and the equinoxes are the best time to visit.
