La Mostra    The patriarchal Basilicas

The Jubilee’s central requirement was to visit the Roman patriarchal basilicas of St Peters, St Pauls, St John Lateran, and St Mary Major. Under the Antiquorum Habet bull, issued in 1300, only visits to the main apostles’ tombs were compulsory for pilgrims. Clement VI added St John in 1350, and Gregory XI included St Mary Major in 1373, which became a pilgrimage destination for the first time during the Jubilee of 1390. With the consolidation of papal supremacy over Rome and transformation of the city and its spaces to burnish the Church’s image, pontiffs undertook significant interventions on the appearance of the basilicas. As well as intervening on their architectural and aesthetic appearance, they made the most of their sacred heritage and built road connections between the basilicas and links to the centre of town. For the basilicas and indeed the rest of Rome, holy years were a spur and an incentive to spruce up. Jubilees also provided an opportunity to raise funds and increase endowments through donations from the faithful. Not only were they places for venerating the most precious Christian relics and spiritual destinations, their artistic glories and human ingenuity inspired admiration in pilgrims and travellers from all over the world. An ever-increasing number of printed guidebooks mapped out itineraries and provided descriptions.
