Some hundred years later the Roman fort of Rigomagus (Gaulish for "king's field") was founded, later to become the city of Remagen.

Many towns were first mentioned in the 9th century, among them Sinzig and the eponymous village of Ahrweiler (since 1969 a part of Bad Neuenahr-Ahrweiler).

The name of Ahrweiler was first noted in the Land Register of the Abbey of Prüm, which during the ninth century, owned almost all of the property in the town.

[2] In 1180, the Holy Roman Emperor Barbarossa chose Sinzig as a place to meet the envoys of France and Flanders.

These families were mainly responsible for the development of Ahrweiler, which then was, together with Bonn, Andernach and Nürburg, one of the capitals of the Archbishopric of Cologne.

In the early years of the Holy Roman Empire there was a county of Ahr, but it was annexed by the Bishop of Cologne in 1246.

But the darkest day in Ahrweiler's history was on May 1, 1689, when the town was razed to the ground, and only ten houses were left standing among the ruins.

[2] The Ahrweiler City Gate and many other historical buildings were partially destroyed at the end of World War II during the contested advances of the Allies.

[citation needed] The 2021 European floods heavily impacted Ahrweiler, where the Ahr river rose, killing at least 135 people.

[5] No member of this community ever returned to Ahrweiler, and today, the town's old synagogue that was desecrated during 1938 Kristallnacht, is used for art displays.

Walporzheim, one kilometre west of Ahrweiler, has some curious rock formations called the "Bunte Kuh" (Colorful Cow) and the "Kaiserstuhl" (Emperor's Chair).

The Ahr river and its smaller affluents serve as a habitat for rare animals, that are adapted to alluvial forests.

Bachem, which lies one kilometre south of Ahrweiler, is also well known for its "Frühburgunder", a local name for Pinot Noir Précoce.
