Adriatic has over 5000 of years history written on its stone sea cliffs; the Austria-Hungary Empire built a number of lighthouses on them in the 19th century. Often located in poorly accessible, isolated locations, lighthouses offer a unique sense of a beauty. Built of white stone, with walls a metre or thicker, lighthouses are among Introduction the most pleasant summer retreats on the Adriatic. Located in landscapes of particular beauty, nowadays they host tourists with adventurous spirits. Unlike the lighthouses in Croatia, lighthouses in Slovenia and northern Italy are not yet regarded as points of interest in the tourism sector even though they bear the same cultural and historical resemblance to those in Croatia.
