Möhn

Möhn is a Roman-era spring sanctuary (German Tempelbezirk von Möhn) in the village of Möhn, municipality of Welschbillig, in the Landkreis Trier-Saarburg, Rhineland-Palatinate, Germany. The complex, recorded as site 1562 ("Heiligtum und Kulttheater Möhn") in the cultural-goods database of the Trier region, comprises three closely spaced temples, a semicircular cult theater, several enclosed springs, and the remains of an adjacent settlement.¹

Key fact	Detail
Character	Gallo-Roman temple complex with three temples, a cult theater, and enclosed springs, interpreted as a spring sanctuary¹
Main deities	Mars Smertulitanus (Mars Smer[---] in the inscription) and Ancamna, named on a limestone statue pedestal; an Apollo relief was also found¹
Date range	Late La Tène period to the late 4th century AD; latest coins struck under Arcadius (395–408); destroyed by fire¹
Coins	About 70 Celtic coins known by 1993; Roman coins number over 2,000, with the largest share from the first half of the 1st and the 4th centuries¹

Location and significance

The sanctuary stands on the southeast slope of the Nosterberg.¹ The site is listed as an ancient place in the Barrington Atlas (sheet 11, grid G3) index of temples and sanctuaries.²

Excavation history

Nineteenth-century digging. After private excavations by one of the landowners in the winter of 1886/87, the complex was investigated archaeologically by the Provincial Museum Trier from April to June 1887. The 1886/1887 work uncovered the remains of three stone temples and a theater at the top of a small valley, near a spring.³

The cult complex

The enclosure wall itself was poorly documented in the 1887 work.¹

The largest building is a Gallo-Roman ambulatory temple (Umgangstempel), a type in which a roofed corridor surrounds the central cella. Its cella measures 11.95 × 13.30 m, with an ambulatory 3 to 3.25 m wide. Several sandstone columns belonging to the ambulatory survive in part, as do pieces of the finely plastered, red-painted parapet walls between the columns. In the ambulatory, excavators found the limestone statue pedestal bearing the fragmentary inscription to Mars Smer[---] and [Anc]amna.⁶ The full reading is generally restored as Mars Smertulitanus with the goddess Ancamna.¹

A second temple adjoins the largest directly to the southwest. A third, smaller building measuring 2.30 × 2.40 m, interpreted in the research literature as a "chapel," stood a few meters away from the three temples. Only its floor screed survived; the walls were missing, probably because they had already been removed in Roman times.

Within the temenos walls, in the northwestern area, a spring was framed with half-cylindrical sandstones. The database entry likewise notes several captured (enclosed) springs and a semicircular cult theater on the slope.¹

Deities and votive practice

The inscription from the temple at Möhn is among the evidence used to identify the epithet of the local Mars as Smertrius.⁴

Votive deposits were varied and numerous. Besides the coins, the finds include weapons (a sword, lance- and arrowheads), rouelles (wheel-shaped votive objects), fibulae, and terracottas.¹ A survey of weapon finds at Roman-period sanctuaries records at Möhn a sword, a shield boss fragment, a large number of lance- and arrowheads, and several horse-gear items, including a phalera of the 1st century and three decorative fittings of the 2nd and 3rd centuries; the probable "ring pommel sword" can be placed in the 2nd and 3rd centuries. The lance- and arrowheads were found between the two walls enclosing the temple precinct, which makes ritual deposition likely.⁵

Coins and chronology

The coin series is the main chronological backbone of the site. The finds from the excavations and later field surveys date the temple district from the late La Tène period, represented among other things by two Nauheim fibulae, into the late 4th century AD.¹ By 1993 about 70 Celtic coins from the site were known, among which late issues predominate; the Roman coins are estimated at more than 2,000, with the largest share from the first half of the 1st century and the 4th century.¹ The high number of coin finds points to coin offerings as a ritual practice.¹

In a comparative study of Iron Age coinage and ritual practice at the sanctuaries of the Martberg, Möhn, and Bastendorf, David Wigg-Wolf, then at the Römisch-Germanische Kommission of the German Archaeological Institute, notes that Iron Age coins are present in significant quantities at all three sites. The Martberg is probably the earliest; at Bastendorf and Möhn the Iron Age coin profile is somewhat younger, and on the coin evidence Möhn is probably to be dated like Bastendorf, whose foundation is placed just after the mid first century BC. Loscheider reconstructed a list of 1,323 coins from the Möhn excavations.³

The sanctuary remained in operation until the end of the 4th century, as the many late-antique coins and restoration work on the buildings show; the latest coins found were struck under the emperor Arcadius, who reigned in the eastern empire from 395 to 408.

The vicus

The remains of a vicus, the civilian settlement attached to the sanctuary, adjoin the temples to the southeast, north, and northeast, but the settlement has not been excavated.¹ Surface finds within its area, including an anvil, iron slag, and tools, attest metalworking there.¹ The find complex extends westward as far as the territory of the neighboring municipality of Newel.¹
