Cleopatra’s palace, Egypt
The grandiose palace of the Egyptian queen Cleopatra was discovered by a French-Egyptian archaeological team in the late 1990s. The palace and the old lighthouse of Alexandria were lost for 1,600 years off the shores of Alexandria in the murky waters of Aboukir Bay as a result of earthquakes and tidal waves.
Thousands of artifacts, including coins, sphinxes, statues and amulets were found in the submerged palace. Many of them were moved in the museums but tourists can dive and explore the palace themselves. The palace might become the world’s first underwater museum.
