Lorun is an Antiquity archaeological site located next to the planned built tourist resort of Červar Porta. The remains of a Roman country villa, an estate consisting of the ceramics workshop, an oil mill and a water cistern were found, while the oldest villa doors coincide with the year 46 BC, the time of the establishment of the Poreč colony under the Caesar. Sisenna Statilie Tauro, a Roman consul for as many as 16 years, owned the estate in the 1st century AD. He was the one who had probably invested in the construction of the economic facilities. Sisienna was an influential man of the time and one of the largest estate owners on the Istrian peninsula. After he had died, the estate first fell under the governance of Kalvia Krispilina, a woman known for her numerous scandals on the court of Nero, and then became a part of the Emperor's agricultural good covering the entire area of Tar and Vabriga.
The names of both these previous owners were confirmed by numerous amphora remains bearing their seals. The Červar villa was greatly expanded during Emperor Tiberius, when the Poreč area and the Červar field became a part of a large agricultural complex for growing and processing olives and grapes. The ceramics workshop, which ovens are the best explored on the Adriatic, closed down in the end of the 1st century. The oil mill might have been operational until the barbarians and the Slavs broke in. They used one of its parts as an oven. The site today is an archaeological park with panels, explanations and photographs of explored facilities, from ceramic ovens to the cistern.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
