The quarry on the island of Sveti Juraj is one of the oldest quarries around Vrsar. It has been exploited since ancient history through the Antiquity and Middle Ages, exclusively for local purposes. The local stone represents the oldest Jurassic material in the area around Vrsar (titone J33 and limestone of the Upper Kimmeridge 2J32).
The quarry on the island of Sveti Juraj is the only systematically exploited deposit of Vrsar stone on the island. This quarry has been known and exploited since ancient history. Stone was hauled from it to the nearby town (located slightly to the northwest of the quarry). It was fully recognised in the Antiquity, when the stone obtained from it was used for the construction of the nearby rustic buildings with the accompanying salt plant and wharf, and in the Middle Ages, when the Church of St George was built from the stone hauled from it. It is a small quarry, exploited exclusively for the purposes of the local construction in Vrsar. This is logical, considering the size of the entire island and the limited exploitation area (i.e. where exploitation was possible and profitable).
With regard to its low altitude, it was the site where the geologically oldest Jurassic material in the area of Vrsar was mined (titone J33 and limestone of the Upper Kimmeridge 2J32). The traces of stone exploitation are obvious, particularly on the highest point of the island and the area around it. The western and southwestern parts of the middle of the island (in relation to the highest point of the island) were exploited the most intensively, as evidenced by an artificial rift with signs of extraction of stone blocks. Furthermore, a kind of a stone cliff was artificially formed by the extraction of stone blocks.
Recent findings have confirmed that the quarry on Sveti Juraj had a great significance, and that it should undoubtedly be counted among the historically most significant exploitation areas of Vrsar stone, being the zone of probably the oldest systematic activity of stone extraction and masonry. In that sense, Sveti Juraj should be regarded as a place where stonemasonry found its beginning as one of the most recognisable activities not only in Vrsar and the surrounding region, but the entire Istrian peninsula.
