Villa Wolkonsky (in Italian, the word villa usually includes not only a large building but also its grounds) is the official residence of the British ambassador to Italy in Rome. The entrance to the villa is located at 4, Via Ludovico di Savoia.
After the Liberation of Rome in 1944, the Italian government sequestrated the property, and it was placed under the Allied Control Commission. For a short time, it was occupied by the Swisslegation and then the Italian Red Cross. When the British Embassy at Rome's Porta Pia was blown up by members of the clandestine militant Zionist group Irgun on 31 October 1946, the Italian government made the Villa Wolkonsky available to the British government to use as a temporary embassy and residence. The United Kingdom purchased the villa in 1951.
When the new British Embassy was reopened at its original location in 1971, the offices moved back to Porta Pia, and the villa reverted to its role as Her Majesty's Ambassador's Residence. On the same grounds are outbuildings containing apartments for senior embassy officials.
The villa itself is frequently used for seminars and workshops, and it is also rented out to appropriate academic or commercial organisations for major events. The extensive grounds were also the venue for the annual Queen's Birthday Party. They are the jewel of the villa, still containing many features originally introduced by Princess Wolkonsky. A recent tree and plant census listed around 200 different species.
