Red Crayfish Pharmacy (Slovak: Lekáreň U červeného raka) is a baroque building and former pharmacy from the 16th century in the Old Town of Bratislava, Slovakia. Since 1953 it houses the Museum of Pharmacy of the Bratislava City Museum. Today, the exhibition features three of the original five rooms of the former pharmacy complete with historical furniture, pharmacy equipment and Baroque – Classicist paintings and wall decorations. The museum contains an original edition of works by Paracelsus from 1574.

The current exhibition displays the history of pharmacy in Bratislava in the first three rooms. The entrance room is furnished with the original Red Crayfish Pharmacy fittings. The furniture set constructed from stained beech in the Empire style standing along three walls of the room is supplemented with a tare balance and a stand for a hand-balance. This equipment is supplemented with faience, stoneware, wooden, china and glass containers for storing medicines dating from a period extending from the end of the 18th century up to the 1950s. The room contains paintings in the Baroque – Classicist style from the end of the 18th century with a theme of healing, with a balustrade and three figurative compositions on the vaulted ceiling.

The pharmaceutical collection contains 8,500 items and 2,880 volumes of ancient pharmaceutical literature and it one of the largest of its kind in Slovakia. It contains original items of pharmaceutical equipment, the oldest originating from the 16th century. The Baroque and Classicist furniture and most of the faience, stoneware, glass, wooden and tin vessels for preserving medicines were made in Slovakia. The oldest dispensing containers, simple tools for the preparation of medicines, laboratory ware and metallic sign-boards were also manufactured within the territory of Slovakia, up to the time of the unification of pharmacies in the second half of the 19th century.

The literature from the 16th century includes an original edition of works by Paracelsus from 1574. The first quadri-lingual tariff of medicines entitled “Taxa pharmaceutica posoniensis”, published in 1745 in Bratislava, which was valid throughout the Kingdom of Hungary is prized locally as an example of the earliest known Slovak pharmaceutical terminology.
