This view was drawn from the steps of the church of Trinità dei Monti.
On the left appears the Palazzo Zuccari, recognizable by its distinctive curved loggia supported by slender columns, still topped at the time by its original trapezoidal roof, later replaced with a modern one.

 

The eye is then led beyond a low building at the corner of Via Gregoriana, opening onto the left side of the city: in the foreground rises the imposing bulk of the Quirinal Palace, crowned by its slender tower. In the distance can be seen the Torre delle Milizie and, in the Colonna gardens, a characteristic umbrella pine.                                                
Closer to the viewer dominates the drum of Sant’Andrea delle Fratte, flanked by Borromini’s elegant bell tower. Further away, the dome of Sant’Agnese in Agone and the tower of the Capitoline can be discerned.
