Built in 1574, it got its name after the 5 wells that were used to supply Zadar with water. Just as the name states, there are five wells lined up one after the other, giving the square a very unique and interesting look. The Square is located between the medieval City Walls and the Renaissance Grimani bastion. There’s also an entrance to the oldest park in Croatia named after Queen Jelena Madijevka and 26m tall Captian’s Tower.

Queen Jelena Madjevka Park is the oldest public park in Zadar, and with this distinction, it has gained its great popularity in the country. It was built on top of the Grimaldi stronghold next to the Square of the Five Wells

Nowadays, the all Walls are protected by UNESCO. The Walls had several entrances, and one of the most impressive ones is the Land Gate (also known as City Gate, or Kopnena vrata in Croatian) Back in the old days, the Land Gate was the main entrance to the city. It’s situated in the Old Town, also known as Zadar Peninsula, near the small Foša harbor. Built in 1543 by Venetian architect Michele Sanmicheli, Land Gate, to this day, still has the status of one of the finest monuments of the Renaissance in Dalmatia.

First built in the 5th century, St. Simeon's Church has undergone alterations until as recently as 1980, and some find the terracotta and white exterior disappointing in comparison with the other churches. This 17th-century church is best known as the home of the mummified body of St. Simeon, one of Zadar’s patron saints. The Chest of Saint Simeon is a rectangular cedarwood sarcophagus in the shape of a chasse, overlaid with silver and silver-gilt plaques, said to hold the relics of St Simon the God-receiver; it is located over the main altar in the Church of Saint Simeon. The chest, considered a masterpiece of medieval art and also a unique monument of the goldsmith's craft of the age, is one of the most interesting works in gold in Europe now under the protection of UNESCO. It was made by local goldsmiths to an Italian design between 1377 and 1380.
