Königshaus, Cultural heritage monument at Leipzig Market, Germany

Königshaus is a landmark at Leipzig's marketplace featuring a baroque facade distinguished by a three-story wooden oriel window on its south side. The building stands at Markt 17 and connects the marketplace front with internal passages leading to neighboring commercial structures.

The house was built around 1560 and rebuilt in 1706/07 by architect Johann Gregor Fuchs for the merchant Andreas Dietrich Apel, keeping the old structure. It was then called Apelsches Haus. The name Königshaus dates only from its conversion into a commercial building in 1904, recalling Augustus the Strong, who stayed here on his Leipzig visits.

The building took its current name in 1904 to honor Augustus the Strong, the Elector of Saxony and King of Poland, who celebrated numerous occasions here. This naming reflects how locals have long connected the marketplace location to the region's royal past.

The ground floor features a passage connecting to nearby Messehofpassage, allowing visitors to explore different sections of the marketplace. Upper levels contain offices and commercial spaces that open to the public during regular business hours.

The spiral staircase inside is a Renaissance Wendelstein of Rochlitz porphyry tuff, added around 1610 together with a cross-vaulted hall that once filled almost the entire ground floor. The staircase survives, though part of the vault was removed during the 1915/16 conversion into a trade-fair building.
