The most western point of Croatia and the former Yugoslavia is the Savudria lighthouse, built in 1818, when it was commissioned by the Austrian emperor Franz I. The antennas for the mobile phones and the IR sensors are of a later date, of course. And, judging by the clothelines, it is still populated.
Also, the Savidria autocamp seems to have expanded all the way to the lighthouse. It is really well maintained, with nice plots and garvel pathways. It must be nice to look at the beam at night….
