On the 19th October 2010, Malta Post issued a commemorative set of four stamps titled 'Treasures of Malta'.
The stamps feature some of the Islands' natural treasures and depict four fascinating sites in the Maltese Islands, the Azure Window - the Natural Arch found at Dwejra Point Cliffs, Blue Grotto – the natural seawater cavern located near Zurrieq, the vertical sea cliffs at Ta'Cenc and the small uninhabited islet of Filfa.
The stamps were designed by the local artist Cedric Galea Pirotta.
