Corfu is the second largest island of the Ionian Islands, and, including its small satellite islands, forms the northwesternmost part of Greece. The principal city of the islandis also named Corfu.
The island is bound up with the history of Greece from the beginnings of Greek mythology. Its history is full of battles and conquests. Castles punctuating strategic locations across the island are a legacy of these struggles.
Two of these castles enclose its capital, which is the only city in Greece to be surrounded in such a way. As a result, Corfu's capital has been officially declared a Kastropolis ("castle city").
In 2007, the city's old quarter was added to the UNESCO World Heritage List. Corfu is a very popular tourist destination.
