At this place stood six or seven forts following on each other.

The first timber and earth fort comes approximately from the year AD 40. Due to the size is presumed, that four centuriae and at the maximum two turmae of the cohors III Gallorum equitata were stationed here. Around the year 42 the fort was enlarged for an additional ala quingenaria.

Between the years 47 and 69 the fort was calculated for an ala. After the batavian revolt (AD 68 - 70) it was enlarged for the deployment of the cohors IIII Thracum equitata (pia fidelis Domitiana).

Around the year 180 the timber fort was replaced by a stone fort and enlarged. To this time the cohors IIII Thracum equitata keeps on seeming to have been present.

Around the year 260 the fort was given up presumably, however at least two granaries were built in the 4th century in the camp. To this time presumably the function of the delta field of the Rhine as a port was re-established. However, the grain had to be stored now protected.

Approx. 1 km south of Praetorium Agrippinae the small settlements along the limes way up to the coast became to an almost closed village. This vicus reached almost the gates of Praetorium Agrippinae. The way at this place was built around the year AD 40 and replaced due to flooding in the year 124. The military used also a part of the field. It existed a small fort for a centuria, horrea and presumably a watch tower. This complex was used from the year 40 up to the middle of the 3rd century.

Today a part of the porta principalis dextra of Praetorium Agrippinae and a part of the limes way are to be seen.
