Predeal is a resort town in the Transylvania region of Romania, in Brașov County. An important mountain resort, Predeal is located on the Prahova Valley and is surrounded by five massifs: Postăvarul, Piatra Mare, Bucegi, Baiului and Fetifoiu. The name is derived from the Slavic word "predel", which means "border", as here was the border crossing between Wallachia and Austria- Hungary before 1918. In the late years the town has known a remarkable boom in construction, with many well-off people from all over the country, having a mountain retreat in Predeal.
