Regensburg: remnants of Castra Regina on the Danube Limes

Regensburg is situated in central Bavaria, and is 1 and 1.5 hours from Nürnberg (Nuremberg) and München (Munich), respectively, with the train. While meandering through the Regensburg’s Old Town, it’s easy to forget most of this area was once occupied by a Roman fortress about 1800 years ago.
In 179 AD/CE, the Roman Empire established the fortress “Castra Regina”, or “fortress by the river Regen”, where the Regen enters the Danube river. The Danube became in effect a part of the Roman Empire’s northern frontier (“Danube Limes”). Emperor Marcus Aurelius recognized the need for extra security in the northern imperial province of Raetia where the Danube’s course reached its northernmost point. To ward off incursions by northern Germanic tribes, up to six thousand soldiers from the Third Italic Legion were stationed at the fortress.
At peak operation, the fortress encompassed an area 540 metres by 450 metres (24 hectares, or 60 acres) with a wall up to 10 metres (33 feet) high made of large sandstone blocks, 18 towers, 4 double-tower gates, and a wide trench. Within the grounds were barracks, headquarters building (principia), commanding officer’s own residence (praetorium), a military hospital (valetudinarium), granary (horrea), workshops, and stables. Civilians and support tradesmen built a settlement to the west of the fort. By the 5th-century, constant raids and migrations forced the Romans to abandon the area. A civilian settlement eventually grew over the fortress which is today’s Altstadt (Old Town)1.
The free-of-charge open-air museum includes restored remnants of the old Roman fortress complete with information displays in both English and German. The primary information location is at the parking garage at Dachauplatz (which is closed at night); the other three locations are accessible outdoors at any time.
The Porta Praetoria is one of multiple constituents in the tri-nation (AT DE SK) inscription for “Frontiers of the Roman Empire: Danube Limes” as UNESCO World Heritage Site (new, as of July 2021).
The map below shows the location of the Castra Regina encampment and locations of the “document Legionslagermauer” in the city’s Old Town. Click on the “arrow-window” icon at the upper-left corner of the map for additional details.
Porta Praetoria
The Porta Praetoria in Regensburg and the Porta Negra in Trier are said to be the only two remaining original Roman city gates in Germany. Regensburg’s Porta Praetoria (Praetorian Gate, Commander’s Gate) was built in 179 AD/CE.
Hunnenplatz, “northeast corner”
Uncovered and freely accessible wall fragments from the Roman fortress along the east section, the northeast corner, and southeast corner make up what is now the “document Legionslagermauer”.
Parkhaus Dachauplatz, “east wall”
The parking garage for Markthalle Regensburg at Dachauplatz was built to incorporate the longest remaining sections of the fortress’ stone wall. This location also houses primary information displays for “document Legionslagermauer.”
Ernst-Reuter-Platz, “southeast corner”
Uncovered and excavated in 1955 and 1961, walls at the fortress’ southeast corner were further renovated in 2013 to include new walkways and illumination. In places along this section there are medieval alterations to the original Roman construction.
Roman provinces, c. 150 AD/CE
Some thirty years before Castra Regina’s completion, the following map around 150 AD/CE shows the Roman Empire’s northern territory in what is now southeast France, southern Luxembourg, southern Germany, western Austria, Switzerland, Liechtenstein, and northern Italy. Civitas Remorum (Reims, France) is at the upper-left; Lugdunum (Lyon, France) is at the lower-left; and Patavium (Padua, Italy) is at the lower-right. At the upper-right is Castra Regina (Regensburg) at the Empire’s northern frontier in the Roman province of Raetia whose capital was Augusta Vindelicorum (present-day Augsburg).

Hi, Cornelia. It’s easy to forget how massive the Roman Empire was, and how the Romans managed to overcome the local populations as far as central England and present-day Palestine. What was interesting was (re-)learning the northern frontier of the Roman Empire against the “hordes” of the Germanic tribes, and that’s what made Castra Regina very interesting for me. Thanks for reading and for your comment!

Indeed. Living here in California, I sometimes forget from what a rich culture I came from.

Cornelia, living in North America it’s sometimes easy to forget that the rest of the world has a lot more recorded history. Difference also is that with First Nations/aboriginal peoples in North America the main facets of their histories are passed on as oral traditions.

in 1971, my cousin took me to see the Roman walls and one of the gates. I remember it was quite a walk. My mother was from Straubing. I remember seeing a sign hanging outside a building where Napoleon stayed when he was in Regensburg. Americans have no idea of the history, they tear down and replace beautiful structures and build parking lots and modern monstrosities.
