Opened in 2004 in the building where the old pharmacy La Reunión was located, this museum is considered the most important pharmaceutical complex in Cuba and one of the largest and most beautiful in the world. Specializing in the history of the most renowned pharmacies in Havana in the mid-19th and the early 20th centuries, it features amazing archaeological items, containers, documents, labels, flasks and sets of old surgical and dental instruments.

The old pharmacy was founded in 1886 by Catalan José Sarrá, and was therefore popularly known as Farmacia Sarrá. This is one of the few cases in which Art Nouveau is more visible in the interior than in the exterior of an inexpressive academicism. Restored by the City Historian’s Office, its carved wood counters and shelves, and stunning modern stained-glass designed by Rosa María de la Terga exhibit an interesting mixture of neo-Gothic and Modernism.
