U Štupartů, Early 20th-century building in Old Town, Prague, Czech Republic.

U Štupartů is an early 20th-century building completed in 1912 in Prague's Old Town, characterized by clean architectural lines and modern elements typical of the period. The structure sits prominently among the winding streets of the historical quarter, with its ordered window patterns and solid facade defining its presence.

The present building was approved on 3 November 1911 and its use was authorised on 28 October 1912, after the original plot was divided into four building sites in March 1911. The monuments commission asked for the old portal to be kept, but this was refused. The house is named after the knight Petr Štupart z Lowenthalu.

The name U Štupartů comes from the knight Petr Štupart of Lowenthal, not from a pub. The new building, completed in 1912, was named after him. The site itself was once the medieval court of Queen Eliška Přemyslovna, possibly the birthplace of Charles IV, and later housed an inn.

The building stands at the corner of Jakubská and Malá Štupartská streets, directly opposite the Church of St James the Greater. The entrance is on Jakubská; the music club and the NSG Morison office are inside. The surrounding lanes are narrow and cobbled, so allow extra time on foot.

The name comes from the knight Petr Štupart of Lowenthal, not from a pub. The medieval three-winged house that stood here was possibly the birthplace of Charles IV, later served as a residence for the Margraves of Meissen and housed an inn before demolition.
