Founding and age
Blankenheim is among the historically particularly well-documented places of the northern Eifel. The earliest documentary traces reach back to the early 8th century, while the actual castle town developed in the High Middle Ages under the protection of a hill castle. For centuries Blankenheim was the centre of an independent county and later an important residence of the Counts of Manderscheid. The present municipality was formed only in 1969 by the amalgamation of numerous previously independent localities.
The actual castle town of Blankenheim grew under the protection of the hill castle built around 1115 by Gerhard I. The complex secured lordship, administration and trade at a favourable traffic location on the western edge of the Ahr hills. Under the lords and later counts of Blankenheim a residence town with fortification, church and market function emerged. The settlement was therefore no chance product, but the result of deliberate lordship formation in the High Medieval Eifel region.
From the High Middle Ages to the end of the Old Empire, Blankenheim was a seat of lordship with changing noble lines. After the extinction of the Counts of Blankenheim in 1406, the estate passed through marriage connections to the houses of Loen and later Manderscheid. Under the Manderscheids the castle was expanded and the water supply was technically modernised via the Tiergarten tunnel. In 1801 the place came under France, in 1815 under Prussia. With the municipal reorganisation of 1969 the present larger municipality was formed, concentrating tourism, local supply and administration in the main town.

First documentary mention |
With the reference “blancium” in the Prüm foundation charter, the area becomes tangible in writing for the first time. The mention documents early ownership relations and an already organized settlement landscape. For local historiography, this year is regarded as the starting point of the documented history of the place. |
| um 1115 |
Construction of Blankenheim Castle |
Gerhard I had the hill castle built above the valley. The castle became the ancestral seat of the Lords of Blankenheim and shaped settlement development in the valley. From then on the place was a centre of rule and at the same time a protected space for trade and crafts. |
| 1380 |
Elevation to the rank of count |
The Lords of Blankenheim were elevated to the rank of count. With this the place rose in the regional hierarchy of rule. The county gained greater political visibility in the Eifel region. |
| 1468 |
Transfer to the Counts of Manderscheid |
Through inheritance and marriage, Blankenheim passed to Dietrich III of Manderscheid. The Manderscheid line reshaped castle and lordship and made Blankenheim a central administrative seat in the Eifel. With this change a long phase of dynastic continuity began. |
| 1468/1469 |
Construction of the Tiergarten tunnel |
To secure the castle’s water supply, Dietrich III had a tunnel driven through the Tiergarten ridge. The structure is regarded as a rare medieval technical monument in Europe. It linked spring, pressure conduit and castle reservoir into a sophisticated supply system. |
| 1505 |
Completion of the parish church of the Assumption of Mary |
The late Gothic parish church in the town centre was completed and became the spiritual centre of the castle town. It still shapes the townscape below the castle today. Building and furnishings reflect Blankenheim’s importance as a residence. |
| 1614 und 1627–1633 |
Witch trials in Blankenheim |
In several waves, people were convicted and executed in witch trials. In 1614 alone, 14 persons were sentenced; in 1627, under witch judge Johannes Möden, further dozens of convictions followed. The events rank among the dark chapters of local history. |
| 1801–1815 |
French period and transfer to Prussia |
After the Peace of Lunéville, Blankenheim, like the left bank of the Rhine, came under French rule. In 1815 the place passed to Prussia by the decisions of the Congress of Vienna. With this the old comital territorial order finally ended. |
| 1. Juli 1969 |
Municipal reorganization into a larger municipality |
Numerous previously independent municipalities were incorporated into the new municipality of Blankenheim. The historic castle town became the central place of a territorially large Eifel municipality. The administrative structure and identity of today’s municipality rest on this amalgamation. |
| 1997/1998 |
Rediscovery of the Tiergarten tunnel |
Archaeological investigations brought the medieval water supply system to light again. Tunnel, construction shafts and well chamber were researched and later made accessible to the public. The find strengthened Blankenheim’s importance as a place of technical and cultural-historical monuments. |
Important information
Blankenheim today stands out as a historic castle town and state-recognised spa and recreational resort in the northern Eifel. The municipality links a medieval townscape, the Ahr spring and a walking region with a living village structure of 17 districts. Tourism, local supply, crafts and municipal public services shape everyday life. For guests and residents alike, Blankenheim is above all experienced as a place where history, landscape and Eifel identity closely belong together.
Blankenheim lies in the southwest of the district of Euskirchen in North Rhine-Westphalia, about 27 kilometres from the district town of Euskirchen. The place is situated on the western edge of the Ahr hills in the northern Eifel and borders Rhineland-Palatinate to the east and south. Its position between Eifel heights, the start of the Ahr valley and important road axes makes Blankenheim a natural hub between the Cologne–Bonn area and the southern Eifel. In landscape and traffic terms the place is both a gateway to the Ahr and part of the wider northern Eifel region.
The municipality extends across a typical upland landscape of forests, meadow valleys, ridges and open plateaus. Protected natural areas in the municipal territory include the Lampertstal juniper reserve and the Nonnenbach valley. Differences in elevation between valley spaces and higher ground shape the landscape and offer wide views across the Eifel. The landscape is at the same time a cultural landscape of villages, pastures, hedges and historic path connections.
Economically Blankenheim relies on tourism, gastronomy, hotels, camping, crafts, small trade and agriculture-related businesses. North of the main town lies a repeatedly expanded commercial area on federal highway 51 with medium-sized firms in construction, mechanical engineering, agricultural technology and food crafts. In districts such as Ahrhütte and Freilingen additional commercial sites are based. Local supply in the main town covers the daily needs of the extensive municipality.
Tourism centres on the Ahr spring, the castle, the timber-framed town centre, museums and a dense network of walking and cycling paths. Blankenheim is the starting point of the Ahrsteig and the Ahr cycle path and lies on the Eifelsteig as well as further theme routes. The cycling and walking station Blankenheim-Wald serves as an important entry point to the region. Campsites, a youth hostel in the castle and seasonal events complement the offer for day and overnight guests.
Culturally Blankenheim is shaped by church art, museum work, carnival tradition and regional heritage care. The Eifel Museum and the Carnival Museum in the Georgstor convey natural, cultural and customary history. The Blankenheim Ghost Procession and the Rose Monday parade are among the best-known local traditions. Concerts, exhibitions and village festivals in the districts keep community life visible.
Landmarks are Blankenheim Castle above the town, the Ahr spring in the timber-framed cellar, and the remains of the town fortification with the Hirtenturm and Georgstor. The late Gothic parish church of St. Mariä Himmelfahrt and numerous timber-framed buildings shape the historic core. The Tiergarten tunnel and the Roman villa extend the ensemble with technical and archaeological monuments. Together they create the image of a compact, historically dense castle town.
The municipality has a town hall, citizens’ office, tourist information, bus station, schools, kindergartens and supply facilities in the main town. Many administrative and information functions are concentrated in and around the Eifel Museum. The extensive municipal area requires good accessibility of the districts via bus lines and MiKE services. For an Eifel commune of this size the infrastructure is comparatively well concentrated, but remains strongly dependent on the central place.
Special features include the Ahr spring captured in a house cellar and the medieval Tiergarten tunnel as a rare hydraulic engineering testimony. Blankenheim carnival with the Ghost Procession is regarded as a distinctive form of custom. Also typical of the region are Eifel cuisine, walking culture and proximity to natural and cultural themes of the northern Eifel. Especially for visitors, the combination of spring, castle and timber-framed town remains unique in the Ahr catchment area.
