Brück House, Art Nouveau residence in Union Square, Timișoara, Romania.

The Brück House is a four-story residential building with a distinctive facade made of ceramic tiles, Hungarian folklore motifs, and enclosed balconies across multiple levels. The street-facing side displays continuous ornamental patterning that defines the entire structure.

A pharmacy called Golden Cross stood on this site from 1898, run by the Geml family (or the Zifkovich family according to other sources). Pharmacist Salamon Brück had the original Viennese Baroque building rebuilt in the Secession style; work began in 1910 under city chief architect László Székely with Arnold Merbl and finished in 1911. After decline post-1989, an Italian owner renovated it in 2012.

The pharmacy on the ground floor has operated since 1898, originally as Golden Cross, and still uses much of its original furniture and display cases. The letters "BS" on the pediment stand for Salamon Brück, the pharmacist who commissioned the 1910 rebuilding.

The ground floor continues to operate as a pharmacy and displays furniture from the 19th century along with colored stained-glass windows above the entrance. Visitors can easily see and admire the building from outside, as it sits on a central square with good accessibility.

Unlike other Secession monuments in Timișoara, the corners of the Brück House were left uncut rather than rounded, a deliberate break from the style's conventions. The letters "BS" on the pediment stand for Salamon Brück, the pharmacist who commissioned the 1910 rebuild.
