Recalada a Bahía Blanca Light, Tallest lighthouse in Southern Hemisphere at Monte Hermoso, Argentina.

Recalada a Bahía Blanca Light is a 67 m cast-iron tower: a central cylinder 1.5 m in diameter, painted red above and white below, ringed by eight cast-iron columns forming an open lattice cone with three horizontal braces. A white gallery and domed lantern sit on top. Its 9 m deep foundations resist the region's strong winds.

The steel components were manufactured by the same French company that built the Eiffel Tower, and operations began on January 1, 1906. It was constructed to help ships navigate into the port of Bahía Blanca, which was rapidly becoming a major export hub for the region.

The name Recalada refers to the landfall ships make before entering the Bahía Blanca estuary; the tower is also called Monte Hermoso Light after the nearby resort. The light station is staffed, and the tower can be visited on guided tours. The sign at its base reads "FARO RECALADA A BAHIA BLANCA".

Visitors can join guided tours and climb 331 steps to explore the interior of this still-active facility. The best times to visit are early morning or late afternoon when lighting is better and crowds are smaller.

The tower's 9-metre-deep foundations were built to withstand the strong winds that sweep the region. Its 1,000-watt lamp produces 1,000,000 candelas, visible nearly 28 nautical miles out at sea. An Automatic Identification System beacon was added on 1 January 2006, a century after the first lighting.
