The site of the cohort fort with an area of 3 hectares is completely built over today. It is positioned in the midst of the modern town and was once the most northern cohort fort on the older Main-line (“ältere Mainlinie”). Amongst the stones which were integrated into the Carolingian Einhard-Basilica is also an inscription stone. Further inscription stones are in the cloister next to the basilica.
