History of Frankfurt Am Main - Early History

Early History

Frankfurt is located in what was originally a swampy portion of the Main valley, a lowland criss-crossed by channels of the river. The oldest parts are therefore to be found on the higher portions of the valley, through which passed the Roman road from Mainz (Roman Moguntiacum) to Heddernheim (Roman Nida). The Odenwald and Spessart ranges surrounded the area, lending a defensive advantage, and placenames show that the lowlands on both sides of the river were originally wooded.

The oldest part of the Altstadt, the old city center, is the Cathedral Hill (Domhügel), upon an island created by arms of the Main. Only from the West could it be reached by foot without getting wet; this, together with its location at a ford, gave it significant military and economic advantages.

Stray archeological finds on the Domhügel go back to the Paleolithic, but the first proven settlement and land development date to the Roman era. It is assumed that the Romans settled on the hill in the last quarter of the 1st century CE; amongst other things, a Roman bath has been found, which may have belonged to a larger complex, possibly a fortress. Apparently the military occupation was abandoned during the 2nd century and replaced by a villa. Several farm buildings have also been excavated. A similar building complex was discovered at the modern Günthersburgpark in the Frankfurt-Bornheim portion of the city.

With the retreat of the Roman border to the west bank of the Rhine in 259/260, the Roman history of Frankfurt came to an end.
