The world’s smallest country that resides inside a city! The Vatican City, is probably the only country you won’t require a passport to travel into. It’s mainly renowned for Apostolic Palace, housing the St Peter’s Square and Basilica. It is also home to The Pope and the location of the Sistine Chapel. Therefore these sites altogether are a vital place of pilgrimage for Catholics. They are also iconic as per their architecture and history which are loved by people. Hours can be spent walking through the seemingly unending halls at the Vatican Museums, which are filled with ancient treasures and artistic relics.
