The private apartment of Princess Isabelle Colonna (1889–1984 ).

"Palazzo Colonna is one of the oldest and largest private palaces of Rome.
Its construction began in the fourteenth century by the Colonna family, who still resides there since eight centuries.
The Colonna family dates back to the twelfth century and comes from the town of Colonna, near Rome, from which it takes its name."
