The newly renovated Archaeological Park has opened in 2014 in Rijeka’s Old Town, at Julije Klović Square. It is an amazing site that shows the ancient history of the city of Rijeka and holds the remains of the Tarsatic Principia, the 3rd century Roman military command that used to be a part of the Roman defence system. The remains of its monumental main entrance, paved central courtyard, and basilica are a jewel of Roman history.
