Arvoredo Lighthouse, Maritime navigation aid in Santa Catarina, Brazil.

Arvoredo Lighthouse stands on an island off Santa Catarina's coast and guides ships with its powerful light beam. The structure displays classic features of lighthouses in this region and shapes the landscape of the protected area.

Construction began in 1878, after the Anhatomirim lighthouse proved invisible in the widest part of the northern channel; the cast-iron tower was prefabricated in England. Inaugurated on 14 March 1883 under the Second Reign, it guides navigation north of Santa Catarina Island. In 2007 solar panels installed through a partnership between Santa Catarina's power utilities, the UFSC solar energy laboratory and the Brazilian Navy began supplying its electricity.

The lighthouse stands on a protected island that local seafarers recognize as a vital navigation landmark. Visitors can see how the structure connects to the marine life and conservation efforts around it.

The lighthouse sits on a protected island that is only accessible under certain conditions. Visitors should check access rules and weather conditions before planning a trip.

The lighthouse was equipped with a Fresnel lens, a then-modern optical system that projects its light across great distances. This technology made it possible to warn ships from far away and gave the building its special place in maritime history.
