« Never cease fighting for freedom »— Historical motto of the city of Zadar
Your quest begins at Foša Old Port in Zadar, a medieval fortified harbor dug in 1574 by the Venetians to protect the city from Ottoman attacks. It was here, on these waters, that Venetian Crusaders led by Doge Enrico Dandolo besieged and conquered Zadar in 1202, during the Fourth Crusade. The bastioned ramparts, approximately 300 meters long, bear witness to 16th-century Venetian architecture. Zadar was then a strategic point for Dalmatian trade, rivaling Venice, which led to its sacking in November 1202. You must find traces of this historical diversion before they are permanently erased.
Continue towards the Monastery and Church of St. Mary, a monastic site founded in the 11th century. The Romanesque church was rebuilt in 1564 by Benedictine nuns, under Venetian rule. This complex, adjacent to the ramparts, houses a pinacotheca with 16th-century works linked to the Republic of Venice. Its 45-meter bell tower, added in 1507, served as a watchtower against Ottoman threats. This site, active since 1091, was a silent witness to the Franciscan and Benedictine presence in medieval Zadar, and may hold compromising documents about the 1202 betrayal.
The Cathedral of St. Anastasia (Katedrala sv. Stošije), built between 1091 and 1166 in Romanesque style, is your next stop. Its facade adorned with 12th-century sculpted portals may conceal coded messages. The main edifice of the Diocese of Zadar since the 11th century, it was damaged during medieval conflicts, including the post-1202 Venetian period. Its 27-meter Romanesque bell tower, completed in 1452, offers views of Foša Old Port and the fortifications. This site is intrinsically linked to Dalmatian ecclesiastical history under Venetian domination, and archives revealing the Doge's profound motivations might be hidden there.
Next, head to the Five Wells Square (Trg pet bunara), built in 1574 by the Venetians. Its five Renaissance wells, each about 13 meters deep, were part of the essential water supply system during Venetian sieges, particularly after the 1202 conquest. Surrounded by 16th-century Venetian palaces, in the heart of the fortified quarter visible from Foša, this square was a crucial hub. The wells, decorated with stone balustrades, with an estimated total capacity of 2000 m³ of rainwater, supplied the besieged city and its occupants, whether Venetian or Crusader. The secrets of a resilient city are buried here.
Finally, your journey will lead you to the Provveditore's Palace (Palača Providurova), a 16th-century Venetian palace. Built around 1560, with its Renaissance loggia and Venetian coat of arms, this residence of the Provveditori of the Republic of Venice in Zadar, less than 500m from Foša, is a symbol of reaffirmed Venetian domination after the 1202 crusade. Its 20-meter wide facade, restored in 2005, preserves Gothic-Renaissance elements. By exploring these historical sites of Zadar, from St. Chrysogonus Church to the Archaeological Museum of Zadar, you piece together the puzzle of Dandolo's betrayal, understanding how the city fought for its freedom, a motto still relevant for Zadar.
