One form of the name Gerolstein first appeared in connection to the building of the Löwenburg in 1115, which was then named the Burg Gerhardstein. Nevertheless, as early as the Stone Age there is evidence of human habitation in the Buchenloch, a nearby cave. In the Bronze Age the Dietzenley was used by the Celts as a refuge castle. In Roman times a temple and dwellings were known to have existed, and remnants of them have been preserved.
Town rights were granted to Gerolstein in 1336. In 1691, the town was almost completely destroyed when it was liberated from French occupation by troops from the Duchy of Jülich. After reconstruction, a devastating fire burnt down the town in 1708. Another likewise disastrous fire occurred in 1784. In the 1801 Treaty of Lunéville Gerolstein, along with all areas on the Rhine's left bank, was given to France, and only returned to German control in 1815. As a landholder Count Sternberg-Manderscheid acquired in the 1803 Reichsdeputationshauptschluss, among other things, the holdings formerly belonging to the monasteries at Weissenau and Schussenried in Upper Swabia to offset his loss of Blankenheim, Jünkerath, Gerolstein and Dollendorf. It is known that water from the spring that had once been used by the Celts and the Romans was being bottled and sold beginning in 1724. This still forms the basis for today’s mineral water industry in Gerolstein. Late in the Second World War, in both 1944 and 1945, Gerolstein’s status as a railway junction town brought Allied air raids down on the town, and 80% of it was destroyed. Town rights were granted Gerolstein once again in 1953.
Bewingen is Gerolstein’s northernmost outlying centre, or Stadtteil, located three kilometres away from the town centre. Here the Kyll flows in a great bow around the mighty dolomite and basalt massif that juts from the west eastwards. The valley narrows and there is only enough room for the railway line, a field road and the river itself. The road finds its way to Gerolstein over the Bewinger Höhe (heights), thus somewhat shortening the way to the nearby middle centre. The local lay of the land was brought about by the local volcanic activity which created two volcanic peaks, the Kasselburgmassiv with the Burlich and the Hahn ("Cock") on the Kyll’s west bank, and the Rockeskyller Kopf on the east, whose volcanic minerals and deposits of lava, ash and cinders from the Quaternary period narrow the river valley.
The place name ending —ingen points to early Frankish settlement. Bewingen was first mentioned in a document in 1218 as a holding of the monastery and church of Niederehe. From that mention it is known that the Brothers Theoderich, Alexander and Albero, from Castle Kerpen established an endowment for the Premonstratensian nuns here in the years between 1162 and 1175. The next documentary mention came in 1282, when "Gerhard VI of Blankenheim" acquired the land, as well as Steffeln, Niederbettingen and Bewingen. In the Middle Ages the lords at Kasselburg (a castle in Pelm) and those at Castle Gerhardstein (Gerolstein) held lands and tithing rights in the village. In the time of French rule, beginning in 1794, Bewingen was assigned to the Mairie ("Mayoralty") of Rockeskyll, and the village remained within the Bürgermeisterei (also "Mayoralty") of Rockeskyll on into Prussian times. The formerly self-administering municipality of Bewingen was amalgamated with the town of Gerolstein in 1969.
One of the verifiably oldest buildings is the small chapel consecrated to Saint Brice which underwent repairs in 1744 and 1745. Its Late Gothic quire suggests that there was an earlier church here, built perhaps about 1500.
Büscheich-Niedereich lies roughly 5 km away from the town centre. In 1352 it had its first documentary mention, although Niedereich’s first documentary mention did not come until 1398.
In 1501, the hereditary estate of Eich (Niedereich) belonged to the County of Gerolstein. On 13 May 1661, the hereditary estate was divided into Niedereich and Obereich.
When the French occupied the Eifel in the 18th century, the Counts lost all their holdings. After the French were driven out the Eifel became Prussian. In 1815 the Prussian government changed Obereich’s name to Büscheich.
The town’s coat of arms consists of a lion rampant sable (black and standing on the left hind foot) armed and langued gules (red tongue, teeth, and claws viable) surmounted at the shoulder by a label of five points of the last.
The town’s arms are actually those formerly borne by the Counts of Gerolstein-Blankenheim, the former landholders. The composition is known from 1567 when it appeared in a seal used by the town’s Schöffen (roughly "lay jurists"). The town has borne these arms since about 1890, but no official approval to do so is known to have been issued.
In addition to the attractions listed below, other things to see in and around Gerolstein include the dried-up maar called Papenkaule, the Buchenloch, a 36-metre-long karst cave that served as a dwelling for Stone Age people, the Mühlsteinhöhlen ("millstone caves") or Eishöhlen ("ice caves") near Roth, a natural history museum and a district local history museum. A walk leads to the Gerolsteiner Dolomiten, a Devonian limestone reef formed by extinct Rugosa, Tabulata and Stromatoporoids with the Hustley, the Munterley and the Auberg. They dominate the town’s appearance, looming 100 meteres above the valley.

On the outskirts of the outlying community of Lissingen stands the formerly moated Lissingen Castle, near the Kyll. The oldest parts of the building date to 1280, although the castle had already been mentioned in documents by 1212. Unlike most castles in the Eifel it was not destroyed. In 1559 it was divided into an upper and lower castle. The lower castle is used as an event and cultural venue.
Gerolstein, Sarresdorfer Straße 17: Evangelical Church of the Redeemer (Erlöserkirche) with Munterley
The EvangelicalErlöserkirche ("Church of the Redeemer") was built between 1907 and 1913 by Franz Schwechten (the same architect who designed, among other things, Berlin’s Kaiser Wilhelm Memorial Church), and was consecrated on 15 October 1913. The inside is decorated with broad gold mosaics, round arches, and a commanding cupola.
Villa Sarabodis is the name given the remnants of a Roman lordly seat – villa rustica. They were unearthed in the course of preparatory work for building the Church of the Redeemer in 1907. The remnants have been dated to the first century AD. The Kirchenbauverein Berlin ("Berlin Church-Building Association"), which also built the Church of the Redeemer, dug the finds up. The foundations and a hypocaust can now be viewed in a protective building.
The Juddekirchhof, as it is known locally, is a Celtic-Roman worship site. It lies above Gerolstein on the Hustley, a part of the Gerolsteiner Dolomiten.
The Roman Marcus Victorius Pellentius had this temple complex built in AD 124. The wall remnants measure roughly 63 by 46 metres. Within this ringwall the foundations of many buildings, among which are two temples, are preserved. One temple was dedicated to Hercules while the other was dedicated to the Celtic goddess Caiva. In 1927 and 1928 remnants of the temple complex were excavated.
