Palacio Barolo’s architecture is based on Dante's Divine Comedy. The 100-meter-tall, neo-Gothic-meets-neo-Romanesque structure was Latin America's highest building when construction was completed in 1923. With 22 floors divided into three sections, the basement and ground floor represent hell, floors 1-14 are purgatory, while 15-22 represent paradise. And there are references at every turn: the nine access vaults represent nine initiation steps while the building’s very height considers the work’s 100 cantos. Topped by a dome complete with a lighthouse–with view that extend to neighboring Uruguay on clear days–it’s a stone’s throw from Congress in Monserrat barrio. This glamorous office block offers tours Monday through Sunday.
