The
Placa has for centuries been the centre of Omišalj. At the beginning of the
20th century, this function was gradually taken over by the area at the
southern edge of the town, the site of the former castle, where the new
municipal building was constructed before World War One. The houses that line
the Placa possess traces of original medieval and Renaissance architecture,
which are hidden beneath the building works, adaptations and renovations that
occurred in the course of later centuries, especially during the 19th and early
20th century, when Omišalj was significantly reshaped.
