Belém Lighthouse, Modern lighthouse in Belém, Brazil.

Belém Lighthouse is a quadrangular concrete tower with four massive legs around a central column, standing 45 meters tall in the Mangal das Garças park. It has two observation platforms open to the public and a lantern at the top. It stands at the confluence of the Guamá and Acará rivers on Guajará Bay.
