The Dannenstern House (Latvian: Dannenšterna nams) is a historical building in the Old town of Riga, Latvia. The house was built by and is named after Ernst Metue von Dannenstern, a wealthy merchant. It dates from 1696 and is considered one of the finest examples of Baroque architecture in Riga. The street facade, in limestone, has giant order Corinthian pilasters and two elaborate entrance portals, created by sculptor D. Walter. The building also contains fragments of an earlier, medieval building.
