Castrum Aequinoctium

Castrum Aequinoctium is a Roman military fort on the Danube in Fischamend, composed of stone foundations and wall sections. The structures reveal Roman construction techniques and military planning, with clear evidence of defensive design and the overall scale of the installation.

The fort was built in the middle of the 1st century AD and underwent reinforcement and repair during Emperor Trajan's reign. These upgrades strengthened defenses against northern tribes and marked a turning point in the development of the Roman defensive line along the Danube.

The name reflects its astronomical location and role as an administrative hub for surrounding settlements. It wove local populations into the Roman economic network, creating connections and oversight across the region.

The site is accessible in nature and can be reached on foot, with archaeological remains mostly visible at ground level. Visitors should wear sturdy shoes and be careful during rain, as the exposed foundations can make the ground slippery.

The fort sat about 14 kilometers from Carnuntum, a larger Roman complex, and formed part of a coordinated defensive network. This proximity allowed rapid communication and mutual support between the two installations.
