Creutznacherhaus, Heritage-listed town house on the market square in Eisenach, Germany

The Creutznacherhaus stands on the south side of Eisenach's Marktplatz at Markt 9, beside the Georgenkirche. Its steep gabled front has half-timbered upper storeys, black beams framing white panels with rows of windows and diagonal braces, above a ground floor of rough golden-brown stone with an arched wooden double door. Small green letters on lower panes spell ZU, VE, MI, ET, RU, HE.

Conrad Creutznacher, a wealthy merchant, had the house built between 1507 and 1539 beside the Georgenkirche; the market portal followed in 1559. Around 1600 Duke Johann Ernst of Saxe-Eisenach bought it and folded it into his town residence on the south side of the market. When that residence was partly demolished around 1742 the house survived and served the finance and justice authorities of Saxe-Weimar-Eisenach and later Thuringia.

The house is called Creutznacher after Conrad Creutznacher, the wealthy merchant and patrician who had it built between 1507 and 1539. Its half-timbered upper storeys, plastered over for a time, were uncovered again during a restoration in 1885. Today the building holds flats, a tourist office and an events hall, and it served as the interim home of the Luther exhibition while the nearby Lutherhaus was being renovated.

The Creutznacherhaus stands on the south side of Eisenach's Marktplatz at Markt 9, directly beside the Georgenkirche. The entrance portal faces the square, and the building now houses apartments, a tourist office and an event hall. Visitors reach the market square on foot from the surrounding old town.

During the 2002–2005 renovation the timber frame was completely dismantled and rebuilt true to the original, reusing surviving original parts; in January 2004 work was briefly halted because ceilings had been illegally broken out. While the neighbouring Luther House was being restored, the Creutznacher House housed the Luther exhibition as a temporary venue.
