This cover from Spain features the EUROPA 2024 stamp which theme is "Underwater Flora and Fauna". A photograph of the underwater forest of the Posidonia oceanica meadows in the Spanish Ses Salines Natural Reserve (Ibiza) illustrates the Spanish Europa stamp in 2024. Ibiza is a Spanish island in the Mediterranean Sea off the eastern coast of Spain. It is 150 kilometres from the city of Valencia. It is the third largest of the Balearic Islands, an autonomous community of Spain. The coast of Ibiza is home to
posidonia oceanica, a seagrass only found in the Mediterranean that supports a diverse coastal and marine ecosystem. The island also contains numerous Phoenician ruins, and the fortified and walled older portions of the city date to the 16th century. Ibiza is a UNESCO World Heritage Site since 1999.
