Antalya, Turkey's principal holiday resort in the Mediterranean region (ancient Pamphylia), is an attractive city with shady palm-lined boulevards, a prize-winning marina on the Mediterranean. In the picturesque old quarter, Kaleici, narrow winding streets and old wooden houses abut the ancient city walls. Lately, many foreigners have bought (and continue to buy) property in and around Antalya for their holidays or for the retirement. It became a popular area especially for the German and Russian nationals. During the winter months its population is around 2,5 million, but in the summer times it doubles.
