Unterkirchberg

Unterkirchberg is a village in the municipality of Illerkirchberg in the Alb-Donau-Kreis of Baden-Württemberg, Germany, first recorded in 1148 as "Chirchberg"¹. It stands at the point where the Weihung valley opens into the Iller valley, with its older part, containing the church, on a Molasse spur between the two rivers¹. The village is notable for two layers of history beneath and around it: a large early Roman fort of the Danube frontier buried in fields north of the settlement, and a medieval castle site associated with the Counts of Kirchberg².

Medieval village and the Counts of Kirchberg

The village belonged from early times to the County of Kirchberg, and Kloster Wiblingen, a Benedictine abbey founded in 1093 about 2.5 km to the north, held property there by around 1100¹^•³. The castle database EBIDAT records that a comital family named after Burg Kirchberg is attested from the second half of the 11th century, and that its original ancestral seat is currently suspected at Unterkirchberg, with Oberkirchberg viewed as a secondary foundation that replaced the older one². Counts Hartmann and Otto, named in 1087, founded Kloster Wiblingen in 1093².

Near the church and cemetery stand the remains of a castle complex, with rubble-stone masonry and a neck ditch 5 meters deep¹. The hill, later called the Kreuzberg, went unused until the end of the 19th century, when the parish priest Sebastian Anton Höpfel planned a Stations of the Cross on it; the way was laid out in 1900, and the hill today carries 14 image posts, a summit cross, and a Lourdes grotto, reached by 107 steps⁴.

Economy and rule. From 1441 the Imperial City of Ulm maintained a toll station at the Iller bridge, collecting a bridge and water toll¹. With the county, Unterkirchberg passed to Bavaria in 1805 and to Württemberg in 1810, then belonged to the Oberamt of Wiblingen and Laupheim and from 1938 to the Landkreis Ulm¹. The parish house in the village served as the summer residence of the abbots of Wiblingen⁵.

St. Martin's church

The Martinskirche, under the patronage of Saint Martin, had a very large parish district until 1819 and belonged to Kloster Wiblingen by 1194; from 1379 it was served by a monk of the abbey¹. The present Catholic parish church was built by Kloster Wiblingen in 1517, restored in 1552 after devastation by soldiers of Margrave Albrecht of Brandenburg, renovated in 1731, given its tower in 1784, and a porch in 1913¹. Late Gothic frescoes in the nave, showing the Coronation of Mary and saints, are by Martin Dreyer, and a substantial rectory of 1763 stands nearby¹. Protestant residents are assigned to Ulm-Wiblingen¹.

The Roman fort

About 200 meters north of the village, excavations in 1928 established a Roman fort, provisionally associated in older literature with the ancient name Phaeniana¹.

Three construction periods are verified.

No written evidence names the troops. A local history account instead describes the garrison as a mounted cohort of 500 soldiers⁶.

Research and remains. Within the southern corner of the wood-and-earth camp, a round palisade ditch half a meter wide was excavated, interpreted as a small amphitheater⁷.

Later history

Alemannic row graves lie near the cemetery, and the village's Catholic registers begin in 1808, when the parish priest Amand Storr started a baptismal register containing a hand-drawn ground plan of the village¹^•⁸.
