Bicentennial Lighthouse, Modern lighthouse in Sarmiento Park, Córdoba, Argentina

The Bicentennial Lighthouse is an 80-metre reinforced concrete tower in Sarmiento Park, designed by Alejandro Cohen in the structural expressionism style as a partial helix with a ninety-degree twist. An antenna on top brings its total height to 102 metres, and at night the tower is lit with LEDs. At its foot, a 1,500-square-metre area holds exhibition rooms and an auditorium.

Planned in 2010 alongside the Centro Cultural Córdoba and the Archivo Histórico, the monument was designed by Alejandro Cohen in the style of structural expressionism. It was built in eight months at a cost of nine million pesos and inaugurated on 2 June 2011 by Governor Juan Schiaretti, though the glass panels of the original project were still missing. At the ceremony Schiaretti said he wanted it to be an icon for the city, like the Monumento a la Bandera in Rosario or the Obelisco in Buenos Aires.

The name honours Argentina's Bicentennial, and Governor Juan Schiaretti presented the tower at its opening as a city icon comparable to Rosario's Monumento a la Bandera or Buenos Aires' Obelisco. In November 2011 a Facebook group jokingly proposed mounting a Bat-Signal on it, citing the nine million pesos of concrete and the lighting bill.

The monument stands in Sarmiento Park, and its 80-metre concrete helix is visible from across the park; the antenna brings the total to 102 metres. The internal stairs to the top are not open to the public, so the structure is seen from outside. The 1,500 square metres at its foot hold exhibition rooms and an auditorium.

The tower is a partial helix: its reinforced concrete body twists ninety degrees from base to top, an example of structural expressionism. The internal stairs to the summit exist but are closed to the public, so the twist is best read from the ground.
