One of the basic principles of proper treatment of geographical names is not to change established and widely used names. The name 'Bay of Piran’ (Cro. Piranski zaljev) is derived from the Italian name Vallone di Pirano 'Bay of Piran', which replaced the Italian name Valle di Sicciole 'Bay of Sečovlje' a century and half ago. This in turn was stablished towards the end of the 18th century, replacing the Italian name Golfo Largone 'Broad Bay'. Since 2000 there have been Croatian attempts to establish the completely new name 'Bay of Savudrija' (Cro. Savudrijska vala).
