Adler Apotheke, Historical pharmacy at Alter Markt, Dortmund, Germany.

The Adler Apotheke occupies a five-storey building with two cellar levels at Am Markt 4, erected in 1912 to designs by Dortmund architects Hugo Steinbach and Paul Lutter and opened in 1914; it is a listed monument. The active dispensary on the left retains the 1864 Gründerzeit fittings of the former Viktoria-Apotheke in Wuppertal, a corner cupboard with columned top sections, its shelves now holding finished medicines with albarelli, syrup jugs and sculptures above.

A document of 1322 names Magister Gerhardus Krudener selling herbs and spices near St. Marien, though the fixed shop came in 1392, when Apteker Mester Willem leased the former cloth house at Am Markt 4 from the city. Around 1500 a merchant added a rear building and leased the dispensary to Dierek Osterwalt of Duisburg. In 1734 Nikolaus Regenherz bought the bankrupt city's pharmacy as a private owner and gave it the name Adler-Apotheke.

The building shapes the character of the old market square with its craft-made facade that visitors notice immediately. The interior shows how pharmacists worked in earlier times and what tools they used.

The pharmacy museum moved in 2017 from the cellar of the active pharmacy to Wißstraße 11, where 300 square metres across 13 rooms now hold over 6,000 exhibits. Guided tours of the private museum are available on request. The dispensing area of the working pharmacy is on the left side of the building at Am Markt 4.

The pharmacy museum opened in the cellars in 2000 with over 6,000 exhibits in eight rooms; in 2017 it moved to Wißstraße 11, where 300 square metres across 13 rooms now hold the collection. The sales room furniture comes from the 1864 Viktoria-Apotheke in Wuppertal.
