The 30-page budget showed it owns 4,051 properties in Italy and about 1,120 abroad, not including its embassies around the world.
Only about 14% of its Italian properties were rented at market rates, while the others were rented at cut rates, many to church employees. About 40% were institutional buildings such as schools, convents and hospitals.
The documentation showed Vatican owns properties as investments in upmarket areas of London, Geneva, Lausanne and Paris.
One building, in London’s South Kensington, led to enormous losses after it was bought by the Vatican’s secretariat of state as an investment in 2014.
On Tuesday, the trial of 10 people in connection with its purchase, including the prominent cardinal Angelo Becciu, starts in the Vatican. They are charged with financial crimes including embezzlement, money laundering, fraud, extortion and abuse of office.
Father Juan Antonio Guerrero Alves, head of the Vatican’s secretariat for the economy, told the official Vatican News website that the building would be sold soon.
Last year, Pope Francis stripped the Secretariat of State of control over its funds. A separate consolidated financial statement for the Holy See issued on Saturday showed a €64.8m deficit in 2020.
