Chuí Lighthouse

Chuí Lighthouse is a tower in Barra do Chuí, Brazil, with a concrete cylindrical structure rising 30 meters high. The lantern section features red and white horizontal stripes, and the tower includes a double balcony for observation.

The original metal skeletal tower from 1910 was replaced in 1941 due to corrosion damage, leading to the construction of the current concrete structure. This change resulted in a more durable building that continues to function today.

The lighthouse marks the southernmost point of Brazilian territory and represents national identity at the border with Uruguay. Visitors notice how this location reflects the geographic and political significance of this southern boundary.

The lighthouse emits two white flashes every 25 seconds, with its beam reaching 46 nautical miles across the South Atlantic waters. Visitors should expect windy conditions and wear sturdy footwear when accessing the base of the structure.

The structure sits just about 1 kilometer from the Uruguayan border and monitors a dangerous 230-kilometer stretch of coastline. This exposed position makes it a critical navigation point for ships traveling through one of the region's most challenging maritime areas.
