History+
Around 200 AD, Jagsthausen was a site on the Upper Germanic-Rhaetian Limes, which once marked the northern border of the Roman Empire. Only about 400 meters from the Limes, in the area of today's park facilities and the northern village center, lay the Roman cohort fort of Jagsthausen. A civilian settlement adjoined to the east, south, and west. Numerous Roman bricks bearing the stamp of the 22nd Roman Legion attest to its presence. The bath itself was likely built around 155 AD together with the fort and renovated around 200 AD under Emperor Septimius Severus, as evidenced by an inscription. Although it was of size, it was a rather simple balineum and not urban thermal baths. A second, smaller bath was renovated again in 247/49 AD before the Limes was abandoned about a decade later, leading to the decay of the structures. Initial excavations took place as early as the 19th century, with a 31-meter-long bathhouse discovered in 1886. Between 1908 and 1913, a Roman-era urn field with around 200 urn graves was uncovered north of the road to Olnhausen.
