The origin of the green dragon can be traced back to an old Slovene legend of Jason and the Argonauts. In addition to the castle, it is one of the main attractions of the city of Ljubljana, symbolizing power, courage and might. Since ancient times, the dragon lives at the top of the castle tower and protects Ljubljana with its people. Four dragons protect “the Dragon Bridge” which has been named after it and crosses the Ljubljanica river. The bridge and the dragons have been designed by architect Jurij Zaninovich in 1900.
