#limes alutanus

• Aluta — The ancient Latin name of the Olt River, frequently used in documents from the Roman Empire period, old cartographic maps, and ancient historical sources. As a structural historical hydronym, it defines one of the most important watercourses on Dacia's territory, along which the Romans built the fortified defensive system known as Limes Alutanus.
• Alutus — The alternative masculine Latin form for the ancient hydronym of the Olt River, documented in vintage maps of the Roman Empire and in the writings of ancient geographers; a hydrographic and strategic axis of vital importance on Dacia's territory. This structural term forms the basis of many archaeological and military designations, defining the natural eastern border fortified by Roman legions with castra and watchtowers.
• Arutela — The name of a Roman castrum and fortified civilian settlement in Dacia Inferior, located on the left bank of the Olt River near the Cozia Monastery in Vâlcea County. This archaeologically significant national site was structurally built by Syrian archers during Emperor Hadrian's reign as part of the Limes Alutanus defensive line, and was partially destroyed by the river's changing course.
