Sea Organ is situated near the new cruiser port, as a part of Zadar's Riva, and can be observed as a differently shaped part of the coast which consists of several stairs that descend into the sea. The stairs extend for about 70 meters along the coast, under them, at the lowest sea-tide level, 35 pipes of different lengths diameters and tilts were built in vertically to the coast and they raise aslant until the paved part of the shore and end in a canal (a service corridor). On the pipes there are LABIUMS (whistles), which play 7 chords of 5 tones. Above the canal there are perforated stone stairs through which the sound comes out when the air pushed by the sea. This site is a blend of human ideas and skills and the energy of the sea, waves, tide and flood, a place for relaxation, contemplation and conversation while listening to an endless concert of mystic harmonies of the "Orchestra of Nature". Sea Organ is constructed according to the project made by architect Nikola Bašić. Our guide told us sometime the sea is very calm and it has to wait for a boat going by to make the wave and the Sea Organ will start to play music again.
Zadar is a historical center of Dalmatia as well as the seat of the Roman Catholic Archdiocese of Zadar. Zadar has important churchs such as Roman Forum, St. Donatus’ Church, and St. Mary’s Church.
We had some free time to wondering around Zadar, then we got on bus and continue to Sibenik. We had a local guide to show us the Old Town. A lot of narrow streets and we climbed uphill to the Medieval Garden of St Lowrence Monastery. Then we walked by the St James’ Cathedral which is on the UNESCO World Heritage List.
Next, we went to Bibich Winery for wine tasting and tapas light lunch. They have produced award winning wines that are exporting to California and New York. They provided 4 different wines for us to taste along with wonderful Croatian style tapas. JC has his birthday that day and the owner gave a bottle of wine to him for celebrating his birthday.
