The Barolo Palace was inaugurated in 1923 and was the tallest building in all of South America until the Kavanagh , in Retiro, was built in 1935. It is almost 100 meters high and is topped by a revolving lighthouse on the 22nd floor.

It was built by the Italian architect Mario Palanti on behalf of the businessman Luigi Barolo, hence its name. According to tradition, it is made up of three parts that correspond to hell, purgatory and heaven in reference to The Divine Comedy by Dante Alighieri, an author of which both were admirers. The style of the building responds to an eclecticism with Gothic and Hindu features of strong expressionism.

In 2010, the City Government promoted the restoration of the lighthouse so that it would participate, with its sparkle, in the Argentine bicentennial festivities.
