We are at the corner of Piazza Colonna with Via dei Bergamaschi, on the left we can recognize Palazzo Chigi with the loggia of the Galleria Deti closed a bit like the one found in Palazzo Bonaparte in Piazza Venezia, in the center the Colonna Antonina with the fountain at its left and behind them Palazzo Piombino which will be demolished in 1889 to make room several years later for the Galleria Colonna (today Alberto Sordi). The buildings on top of Palazzo Piombino are very strange, does anyone know more? Thank you.
