Governorate's Palace, Administrative palace in Vatican City.

The Governorate's Palace (Palazzo del Governatorato) stands in the Vatican Gardens directly behind St. Peter's Basilica. It was formed by joining three massive adjoining buildings, built between 1927 and 1931 in eclectic style by the Piedmontese engineer Giuseppe Momo, architect of the Reverenda Fabbrica di San Pietro. Attached to the complex is the church of Santa Maria Regina della Famiglia, formerly Santa Marta, also designed by Momo.

The palace was completed in 1931 by architect Giuseppe Momo, just a few years after the Lateran Treaty of 1929 established Vatican City as an independent state. It was built from the start to serve as the seat of the new state's civil administration.

The Governorate's Palace houses the offices that run Vatican City as a territory, separate from the Church's religious functions. Visitors who walk through the Vatican Gardens can see how the building sits apart from the surrounding religious spaces, giving a sense of the Vatican's dual nature as both a state and a holy site.

The palace can be seen from the outside during guided tours of the Vatican Gardens, which need to be booked in advance. The interior is not open to the public since the building is still in active use as a government office.

The architect Giuseppe Momo, who designed this palace, is better known for the double-helix spiral staircase inside the Vatican Museums, which he also created. Both works come from the same period and stand only a short walk apart.
