Brittenburg, Roman military granary in Katwijk, Netherlands
The Brittenburg fortress contained stone walls and round towers at the mouth of the Rhine River, serving as a strategic military outpost.
Archaeological excavations in 1520 revealed Roman artifacts, including coins dating back to 270 CE, when storms exposed the entire complex.
Fishermen from Katwijk referred to underwater ruins as the tower of Kalla, maintaining the memory of this ancient structure through generations.
The site lies approximately one kilometer west of the European Space Research and Technology Centre, now submerged beneath the North Sea.
The square inner structure indicates the building functioned as a lighthouse reaching 60 meters high, similar to the lighthouse at Ostia Antica.
