Mannaricum: fort in the Roman Rhine limes, modern Maurik in the Netherlands.
Stray finds from this area suggest occupation by soldiers after 70 (the year of the Batavian revolt), and perhaps earlier. Probably, the fort was rebuilt in the first quarter of the third century, and evacuated in 275 - like so many other forts along the Lower Rhine. Potsherds and coins suggest a renewed occupation in the fourth century.
Two military units can be identified: around 83, the Second equestrian cohort of Thracians (cohors II Thracum equitata) was replaced by the Second Spanish equestrian cohort (cohors II Hispanorum equitata). It is interesting to note that the First equestrian cohort of Thracians (cohors I Thracum equitata) was stationed in nearby Rijswijk.
It is probably impossible to excavate the remains of the Roman fort because most artifacts have, until now, been found close to the meandering Rhine.
