The white mulberry tree, known as Šimun's Mulberry, is considered the oldest tree in Šibenik's historic center. It is estimated to be about 150 years old, and its trunk circumference exceeds three meters, making it an impressive witness to times past.

According to legend, the sailor Šimun, a member of the Confraternity of St. Nicholas consisting of sailors and shipbuilders, brought a mulberry seed from distant China and planted it next to the Church of St. Nicholas as an act of penance. Although the legend dates the planting of the tree to the 17th century, Šimun's Mulberry is actually the only surviving tree from the former row of mulberry trees on the Fruit Square (Voćni trg), which was destroyed during the Allied bombing in 1943.

In the past, mulberry trees were popular for providing shade and were intentionally planted in Dalmatian squares and along coastal promenades. Today, Šimun's Mulberry is a valuable example of such a heritage tree and a place where nature, history, and local stories meet in the very heart of Šibenik.

Visiting this green witness to the past offers an opportunity for a short break while exploring the old town center, as well as a chance to discover a lesser-known layer of Šibenik's heritage that connects maritime tradition, urban space, and the power of nature.
