All Saints' Day, also known as All Hallows' Day, is a Christian festival celebrated in honor of all the saints, known and unknown. In Vatican City, this holiday is observed with much reverence and solemnity, due to the city-state's strong Catholic heritage. The festivity is marked on the 1st of November each year, serving to remember all saints and martyrs throughout Christian history.
On this day, Vatican City becomes a venue for religious events as the Pope leads the faithful in prayer and contemplation. Ceremonial masses and services are held in the Saint Peter's Basilica, one of the largest and most significant Catholic shrines worldwide. The Holy See calls for reflection on the virtues of the saints - their faith, love, charity, and sacrifice - as a means of inspiring the worldwide community of believers.
It is tradition during All Saints' Day in Vatican City for the Pope to recite the Angelus prayer at noon in Saint Peter's Square - following which he offers his apostolic blessing. This day is not only a public holiday in Vatican City but also in other Catholic-majority countries worldwide. The occasion is deemed a holy day of obligation, meaning that Catholics are required to attend mass. All Saints' Day marks a time of remembrance, spiritual engagement, and Vatican City, filled with rich narratives of saints, stands as a meaningful backdrop of this day.
