On 4th December 1999, UNESCO inscribed Eivissa, Biodiversity and Culture as a World Heritage Site for its millenary culture and rich biodiversity.
UNESCO declared the Acropolis of Dalt Vila (the old town of Eivissa), the Posidonia oceanica meadows, the Phoenician-Punic necropolis of Puig des Molins and the Phoenician settlement of Sa Caleta, vestiges of the first settlements on the islands, as World Heritage Sites.
The intaglio stamp dedicated by Correos Correos in its series Conjuntos Urbanos Patrimonios de la Humanidad (World Heritage Urban Sites), shows a detail of Dalt Vila, a spectacular monument to history.
Among its winding streets, you can see the traces of all the cultures that have passed through the island, from the first settlers of the city's bay, to the Phoenicians, Carthaginians, Romans and Muslims, .....
The impressive Renaissance walls crown the island's capital. They were erected in the 16th century by the Spanish Crown, according to a design by the Italian Giovani Battista Calvi. The complex is made up of seven arrowhead bastions that embrace a perimeter of 1,800 metres.
The necropolis of Puig des Molins was founded by the Phoenicians in the 7th century BC and houses some 3,000 hypogea excavated in the rock. In the municipality of Sant Josep is the Phoenician settlement of Sa Caleta, an archaeological site dating from the 8th century BC, which is the first settlement on the island.
The posidonia meadows are the cause of the spectacular beauty and transparency of the waters off its coasts.
Therefore, their conservation is of vital importance, as the unique biodiversity of the waters of Eivissa and Formentera depends directly on their protection and care. These posidonia meadows of Eivissa and Formentera are a world heritage whose loss would be an irretrievable catastrophe.
