Known as the Eternal Capital, Rome's layers of history are presented to visitors in the form of classical ruins, early places of worship, ancient fountains and Renaissance palazzos. Against this dramatic backdrop, where centuries of different architectural styles vie for the visitor's attention, you will find a modern, vibrant city with a smorgasbord of activities, eateries and museums. Must-sees in Rome include the iconic Colosseum, the city's most classical ruin which, at its peak, seated over 50,000 people, as well as the former Roman temple- turned- church, the Pantheon. Marvel at the 50 meter wide Trevi Fountain, Rome's largest Baroque fountain, and the beautiful façade and interior of the Basilica di Santa Maria Maggiore. Pay a visit to one of the most ancient parts of the city, the Palatine Hill full of dramatic archaeological ruins. The Borghese Gallery contains one of the world's greatest art collections, with hundreds of statues and other artefacts, while the Doria Pamphilj Gallery is famous not only for its incredible pieces of art but also for its palazzo in where the works are displayed. The Vatican Museums, with their piece de resistance being Michelangelo's Sistine Chapel, are also home to classical statues, frescoes and other decorations. A visitor's biggest challenge in Rome is to decide how to cram in as much as time limitations allow, without doing so much that the true masterpieces in art and architecture are overlooked. Reach a good balance by taking some time out to sit at pavement cafes and people-watch, in order to pick up the slower pace of Rome.
