General view of the construction site of a major underground hub in central Piazza Venezia in Rome, Thursday, May 9, 2024. The Vatican crosses a key milestone Thursday in the runup to its 2025 Jubilee with the promulgation of the official decree establishing the Holy Year. For the next four years at least, central Piazza Venezia and its Imperial Forum-flanked boulevard to the Colosseum are scheduled to be congested and blighted by giant, 14-meter (yard) high green silos that are needed for the subway drilling operation under way.
