The Alexanderturm is a rare medieval tower in Mainz, built around 1500 atop Roman foundations dating back to the 4th century. Located on the grounds of the Kupferberg Sektkellerei in the Oberstadt district, the tower marks a historic bend in the ancient city wall where Roman and medieval fortifications once converged. Though not publicly accessible, the Alexanderturm remains one of three surviving towers from Mainz’s former city defenses, alongside the Holzturm and Eisenturm. Its cylindrical form and strategic placement reflect its original role as a watchtower guarding the western flank of Mogontiacum, the Roman precursor to Mainz. The site’s layered history—from Roman castrum to medieval stronghold—embodies the city’s enduring legacy as a crossroads of military, civic, and architectural evolution.
Mainz GermanyThe Alexanderturm in Mainz is a late medieval city tower located on the private grounds of the Kupferberg-Sektkellerei in the Kästrich district of Mainz, specifically at Kupferbergterrasse 15, 55116 Mainz. This tower stands on the foundation of a Roman round tower and is surrounded by the picturesque vineyards of the Kupferberg winery. Nearby, visitors will find the Novotel Mainz hotel and charming restaurants, making the area a blend of historic ambiance and modern leisure. The tower is set away from the busy old town, offering a peaceful atmosphere close to the wine culture for which Mainz is well known, providing an appealing destination for both history enthusiasts and those looking to enjoy local wine and scenic views.
