Marco Zero, Equator monument in Macapá, Brazil.
Marco Zero is a circular monument with a 30-meter obelisk standing at the exact location where the equatorial line crosses through Brazil's northern region. The site features informational panels explaining the solar phenomena and geographical position that define this location.
The monument was inaugurated in 1987 to mark Macapá's geographical significance as one of Brazil's few cities on the equatorial line. Its construction recognized this distinctive geographical characteristic that sets the city apart.
The monument serves as a gathering place during equinox festivals in March and September, when musicians perform and local artisans display handmade goods. These celebrations connect the community to the astronomical events that define this geographical location.
The monument sits about 6 kilometers from downtown and is best visited during clear weather when sunlight is strongest. Allow time to read the informational displays and bring sun protection, as the area offers minimal shade.
During equinoxes, sunlight passes through a circular opening at the top of the obelisk and projects directly onto the ground below. This optical effect occurs only twice yearly and creates a memorable moment when astronomical events align perfectly with the building's design.
