*Kavanagh building is located at 1065 Florida St. in the barrio of Retiro, overlooking Plaza San Martín. It was constructed in the 1930s in the Rationalist style by the architects Gregorio Sánchez, Ernesto Lagos and Luis María de la Torre, and finished in 1936. The building's features include austere lines, lack of external ornamentation, and large prismatic volumes. It was declared a national historical monument in 1999, and is one of the most impressive architectural masterpieces of Buenos Aires. Standing at a height of 120 m, it still retains its impact against the city's modern skyline. In 1939 its façade received an award from the American Institute of Architects.
