Founded in 1908 by Signora Gilda Bacci, the pharmacy was located on the ground floor of the fifteenth-century Palazzo Dati, a site it still occupies today. It has retained its original furnishings consisting of glass-fronted shelves, enamelled white and gold with columns, capitals and corbels joined at the top by a frame bordered in gold. In 1956 the counter, originally at the centre of the room, was moved to the right and a new cabinet in antique style was built.
