Bismarckstraße 50, Cultural heritage monument in Heilbronn, Germany.

Villa Frau Alfred Knorr is a late Historicist villa built in 1896, elevated on Bismarckstraße 50 in Heilbronn. Its sandstone facade combines Gothic and Renaissance ornaments, and a carved family coat of arms with three hands holding fish and the initials 'AK' sits above a second-floor window on the north-west corner. A 4,767 m² park with old trees surrounds the house, and a coachman's house with a pointed tower was added behind it in 1904.

Marie Therese Knorr, widow of factory owner Alfred Knorr, commissioned the villa in 1896 from architects Ernst Walter and Karl Luckscheiter; it cost 200,000 gold marks. Her daughter Anna Keiper-Knorr sold it to the Wehrmacht in 1937 for 136,000 Reichsmark. After World War II it became federal property, housed the Heilbronn district court from 1947, later served as a military recruitment office until 1994, and was sold to a private owner in 1996.

The carved stone emblem on the north-west corner marks the owner's identity and status through Gothic design elements. These details show how the house displayed wealth and family pride to visitors at the time.

The villa at Bismarckstraße 50 is a private residence, so visits are limited to viewing the sandstone facade and the 4,767 m² park from the public street; the grounds and interior are not open to visitors. The carriage house with its pointed tower (No. 50a) stands behind the main building and can be spotted from outside.

The nameplate reading "Frau Alfred Knorr" once hung on the property's entrance gate, and a sandstone coat of arms above a second-floor window on the north-west corner shows three hands each gripping a fish beside Alfred Knorr's initials "AK", framed by a Gothic pointed arch.
