Detail of an old elevator inside Palacio Barolo. Monserrat, Buenos Aires, Argentina.

Palacio Barolo was designed by the Italian architect Mario Palanti according to the Dante's Divine Comedy. There are 22 floors, divided into three "sections". The basement and ground floor represent hell, floors 1-14 are the purgatory, and 15-22 represent heaven. The building is 100 meters (330 feet) tall, one meter for each canto of the Divine Comedy. The lighthouse at the top of the building can be seen all the way in Montevideo (Uruguay). The building was declared a national historic monument in 1997. When it was built it was the tallest building in the city and South America. Its twin brother, Palacio Salvo, is a building designed and erected in Eclectic style, but of greater height, built by the same architect in Montevideo.
