The UNESCO World Heritage Committee declared a World Heritage Site Humanity the walled enclosure of Dalt Vila in 1999, when considering it the best preserved coastal fortress in the Mediterranean.
Ibiza preserves considerable evidence of its long history through the Phoenician remains of sa Caleta or the Phoenician-Punic necropolis of Puig des Molins. They are an exceptional testimony to the urbanization and social life of the Phoenician colonies in the western Mediterranean.
There is also an important historical and cultural heritage scattered throughout the territory. These include the sacred mountains of Santa Eulària and Sant Miquel, the fortress-churches scattered throughout all the municipalities, the unique defense towers or the wells and pools of Arab origin, declared a Site of Cultural Interest.
Throughout its history, Ibiza has always interacted with other cultures. Punics and Phoenicians, Romans, Arabs ... They all surrendered to its brilliant light, the purity of its sky and the transparency of its waters.
Furthermore, biodiversity and culture provide an excellent example of the interaction between marine and coastal ecosystems.
The relevance of the marine environment on the island lies mainly in the dense meadows of posidonia oceanica that make up its sea. The grasslands are home to some 220 different species that form the most important marine community in the Mediterranean. All these values made Ibiza become part of the select “club” of World Heritage cities.
