The island of Capri is in the Tyrrhenian Sea, off the west coast of Italy. It is one of Europe’s most beautiful islands. There are many things to see and do on the island. In Capri city, you can buy clothes in the fashionable boutiques and eat delicious Italian food in one of the cosy restaurants on the harbour. You can also go sightseeing in Capri. If you like history, you can explore the ruins of the villas that Roman emperors built on the island. The Villa San Michele, for example, has got a wonderful garden with works of art from Ancient Egypt and Rome. The garden has also got an amazing view of the island. You can even see Mount Vesuvius, the famous volcano in Naples, from the garden. Capri’s most famous attraction is the Blue Grotto. It’s a sea cave on the northwest coast of the island. Inside the cave, you can see an amazing blue colour in the water. It was once the swimming pool of the Roman emperor Tiberius. Capri is also a popular destination for many painters, writers and musicians. They come to Capri to enjoy the peace and quiet of the island. In the past, the writer Graham Greene stayed on Capri, and today the singer Mariah Carey owns a villa on the island.
