A roofless palace in Italy's Viterbo hosted the first and longest conclave
- In November 1268, cardinals gathered in Viterbo, Italy to elect Pope Clement IV's successor in the longest papal election.
- The conclave lasted 1,006 days because strong divisions among cardinals and political factions delayed consensus until September 1271.
- Citizens, frustrated by funding the cardinals' stay, restricted their meals and exposed them by removing the roof of the palace’s main hall.
- A parchment dated June 8, 1270 records that the cardinals were locked inside a 'palazzo discoperto', meaning a palace without a roof.
- The election ended with Gregory X, who established strict conclave rules in Ubi Periculum that shaped future papal elections and shortened durations.
