As a result, Corfu’s capital has been officially declared a Kastropolis (“castle city”) by the Greek government. From medieval times and into the 17th century, the island, having successfully repulsed the Ottomans during several sieges, was recognised as a bulwark of the European States against the Ottoman Empire and became one of the most fortified places in Europe.
The fortifications of the island were used by the Venetians to defend against Ottoman intrusion into the Adriatic. Corfu eventually fell under British rule following the Napoleonic Wars, and was eventually ceded to Greece by the British Empire along with the remaining islands of the United States of the Ionian Islands. Unification with modern Greece was concluded in 1864 under the Treaty of London. Corfu is the origin of the Ionian Academy, the first university of the modern Greek state, and the Nobile Teatro di San Giacomo di Corfù, the first Greek theatre and opera house of modern Greece. The first governor of independent Greece after the revolution of 1821, founder of the modern Greek state, and distinguished European diplomat Ioannis Kapodistrias was born in Corfu.
In 2007, the city’s old town was added to the UNESCO World Heritage List, following a recommendation by ICOMOS.
The island is a very popular tourist destination.
