In 1919, the construction of Palacio Barolo began. This was South America's tallest building at the time and was the first Argentine skyscraper built with concrete (1919–1923). The building was equipped with 9 elevators, plus a -high lobby hall with paintings in the ceiling and Latin phrases embossed in golden bronze letters. A 300,000-candela beacon was installed at the top (110 m), making the building visible even from Uruguay. In 2009, the Barolo Palace went under an exhaustive restoration, and the beacon was made operational again.
