Obelisco in Buenos Aires is a slender concrete monument rising above Plaza de la República at the junction of Avenida 9 de Julio and Corrientes, a point where colonial dates and multi-lane traffic meet in one vertical marker.Plaza de la República at 9 de Julio and Corrientes The tower was inaugurated on 23 May 1936, four centuries after Pedro de Mendoza’s first foundation of Buenos Aires, and designed by Argentine modernist architect Alberto Prebisch.built in 1936 for the 400th anniversary
A modernist needle of reinforced concrete
Seen from street level, Obelisco is a simple four-sided shaft of reinforced concrete, its pale cladding sharply set against the darker asphalt and surrounding buildings.reinforced concrete monument with stone cladding It stands about 67.5 m (221 ft) high on a square base of roughly 6.8 m per side, rising from a small island in the centre of the traffic flows along Avenida 9 de Julio.67.5 metres high on a 6.8 metre base
The architect Alberto Prebisch, a leading figure in Argentine modernism, gave the structure sharp edges and plain surfaces rather than ornament, placing it at a point where the diagonal line of Corrientes crosses the broad north–south axis of 9 de Julio.designed by Alberto Prebisch Up close, the faces of the monument show simple inscriptions that tie the concrete to particular dates, including references to the founding of Buenos Aires and the raising of the national flag at this spot.
History written into a traffic island
The monument’s date, 1936, fixes it in an era when Buenos Aires was reshaping its central grid with wide avenues, and Plaza de la República emerged as a new open space amid older blocks.construction began in March 1936 and finished in May Obelisco marks four hundred years since Pedro de Mendoza’s first attempt to establish a Spanish settlement here in 1536, a short-lived foundation that nonetheless became a starting point for later urban and national history.commemorating the 1536 foundation by Pedro de Mendoza
The structure also stands on the site where the Argentine national flag was first raised in the city, a link that turns the concrete shaft into a marker for both civic and national memory.site of the first flag raising in the city Inside, an internal staircase of over 200 steps climbs to the top, a narrow route used for maintenance and occasional official visits rather than everyday access.206-step staircase inside the monument
Obelisco in the Buenos Aires cityscape
From many directions, the monument appears at the end of long straight views, its point cutting the line of rooftops along Corrientes with theatre marquees and office blocks framing the concrete shaft. The Gran Rex Theatre, another of Alberto Prebisch’s works, stands nearby on Corrientes, anchoring the architect’s modernist language in both cultural and commemorative buildings.Gran Rex Theatre on Corrientes
Plaza de la República itself is a paved island amid moving traffic and pedestrian crossings, with Obelisco rising from its centre as a fixed point in the flow. The tower’s proportions place most of its height in the long stretch of shaft before the upper taper, a balance that keeps the overall form strong when seen from ground level or at a distance along Avenida 9 de Julio.67.5 metres of height with a long shaft below the apex
