Avignon, located in the central region of Provence, is one of the most important cities in southeast France. Known as the "City of Popes," Avignon became a prominent religious center when Pope Clement V relocated the Catholic Church's papacy from Rome to Avignon in 1309, a period that lasted until 1378 under the control of King Philip the Fair. As a result of this papal relocation, Avignon became a pilgrimage site for devout Catholics, preserving numerous religious buildings in its city center.

Among the most famous of these religious buildings is the Palais des Papes, or Papal Palace. This historic fortress, which was built to house the papal court and to defend the city from attack, is considered one of the best-preserved medieval palaces in existence. In 1995, the historic city center of Avignon was declared a World Heritage site by UNESCO, recognized as a unique and irreplaceable testimony to the power and wealth of the papacy in the 14th century.

Today, Avignon is a lively city that still retains its medieval charm, with its narrow streets, quaint alleyways, and beautiful Provencal architecture. The city is a popular tourist destination, attracting visitors from around the world to explore its rich history and culture. With its blend of ancient and modern, Avignon offers a truly unique experience to visitors.
