Schweiger House, Historic residential building in Old Square, Ljubljana, Slovenia.

The Schweiger House is a late-Baroque building at Stari trg 11a, its facade asymmetrical, six bays wide and three storeys high. Above the entrance portal stands the statue of the Molčalac (Schweiger), and the semicircular pediment carries the coats of arms of its former owners. The interior is the work of architect Candido Zulliani.

The house stands on the site of several narrower, older townhouses and was rebuilt in 1748–49, when its asymmetrical six-axis facade received the two coats of arms of its then owners. Its interior is the work of architect Candido Zulliani and, after the loss of his other Ljubljana buildings, is his most important surviving work. It is named after the Schweiger von Lerchenfeld family, its first owners.

The house is named after the Molčalac (German: Schweiger) statue above the entrance portal, a figure with a finger to its lips. The Schweiger von Lerchenfeld family coat of arms appears in the semicircular gable of the facade, alongside another owner's coat of arms. A bronze bust of poet Lili Novy, who lived here most of her life, is mounted at the entrance.

The house stands at Stari trg 11a, the only address on a main square of Ljubljana's old town to carry the letter "a". The asymmetrical six-axis facade and the Molčalac statue above the portal are best seen from the square itself, on foot.

The house is named after the Molčalac (German: Schweiger) statue above the entrance portal, whose finger-to-mouth gesture gives the Schweiger surname its meaning of 'the silent one'. The address Stari trg 11a is the only house with an 'a' suffix on any of the main squares of Ljubljana's old town.
