Lutherplatz 7, Heritage monument in Schmalkalden, Germany.

Lutherplatz 7 is a three-story half-timbered house whose front section, facing Lutherplatz, dates from around 1520 and is covered by a hipped roof (Krüppelwalmdach). Its rear building was already built around 1365. The timber frame features quarter-circle foot arches, and the house was altered in the 17th century.

Martin Luther stayed in this house in 1537 during the Schmalkaldic League's assembly in Schmalkalden. A painted plaque with an inscription from 1687 on the facade recalls that meeting. The front building dates from around 1520, while the rear wing was already built around 1365; the house was altered in the 17th century.

The name Lutherhaus recalls Luther's stay in 1537, when he is said to have preached in the Große Diele, whose painted wooden ceiling rests on stuccoed lions and four angels bearing the attributes of the seasons. On the second floor a fully sculpted swan stands before a plaque with the coats of arms of Luther and Melanchthon.

The building is located in the town center and can easily be reached on foot, as several other historic landmarks are nearby. Visitors can view the structure from the outside and admire its exterior details, though access to the interior may be limited.

On the ground floor wall, visitors can spot the builder's mark from the 16th century, a round symbol surrounded by three cannonballs. This rare craftsman's mark was an old practice used to authenticate and identify the master builder's work.
