North Dalmatian island of Murter is located in the northwestern part of the Šibenik-Knin County. The island is separated from the mainland by the Murter Canal. Island was connected whith mainland by the end of the 18th century. The earliest traces of human activity date back to the Neolithic period, however, these earliest artifacts have been lost. At the end of the Bronze Age, a settlement emerged in today's Gradina position, which lasted throughout the Iron Age and partly through the Roman period. From the second century onwards, elevated positions began to vacate. Witnesses to the continuous life are grave finds from the neighboring island of Mali Vinik, as well as from the Zdrača site south of Gradina, and numerous other small finds, especially ceramic ones, which are scattered throughout the site. City from Roman period was active on west side, where numerous architectural remains are still visible, and archaeological research has found a large number of various archaeological artifacts as well as architectural remains. The ancient and late antique writers of Gaius Pliny Secundo, Claudius Ptolemy and Anonymous of Ravenna in their works mention Colentum either as an island or as an island settlement (polis). Numismatic and other small archeological findings suggest that the Roman Colentum continued its life through the period of late antiquity, after which it was very likely interrupted for a short time. The witness that this interruption was of short duration is built into the southern wall of the present-day church of Gospa of Gradina, which contains a cross with extended arms and dates to the 6th century. The site of today's cemetery housed an old Croatian necropolis with two burials recorded, as well as a burial architecture indicating the existence of a third deceased. The finds found in the graves date from the 9th and 10th centuries. The earliest shipwreck of the Murter aquatorium dates back to the 6th century BC. The latest ones date back to the 18th century and are a witness to a long navigation tradition in the Murter area, and the archeological artifacts found there help us to better understand the daily life of the island's previous inhabitants.
