Am Römerturm 3, Heritage building in Altstadt-Nord, Cologne, Germany.

Am Römerturm 3 is a protected heritage building with residential and commercial spaces across multiple floors in Cologne's northern old town. It occupies a site that once held sections of the ancient Roman fortifications protecting the city.

The building was designed by architect Friedrich Wilhelm Kraemer on land where Roman fortifications once stood to defend the ancient city. It physically connects two layers of the city's past in a single location.

The building sits close to the historic Roman Tower and helps shape the character of this old neighborhood. Its presence reminds visitors how different periods layer together to create what the district feels like today.

The heritage monument is protected by strict preservation rules, meaning any changes to its exterior need special approval before work can begin. Visitors should know that this is an active residential and commercial building that can only be viewed from outside.

The vaulted cellar of the former Parfusenhof from the early 13th century survives beneath the house and is used today as the "Sancta-Clara-Keller" events room. It hosted the 700th anniversary of the consecration of the St. Clara convent on 12 August 2006, attended by Minister-President Jürgen Rüttgers, Mayor Fritz Schramma and auxiliary bishop Heiner Koch.
