In the stone barn next to Millennium Square, you’ll find the Apothecary’s Hall, a late 19th century pharmacy where most medicines were made from plant materials and extracts. Here you will see a range of ‘shop rounds’ containing tinctures, syrups and powders. These were chiefly used to produce pills, ointments and potions using the kind of mortars and balances that are on display. Compare the wide range of  proprietary medicines, and their exaggerated claims, against the products of today.

You also have a rare chance to read a real prescription book, written in Latin.

Above the counter, you cannot miss the magic mirror. This unique look-back in time offers a series of short stories about an Edwardian apothecary and his apprentice. Each 3-4 minute vignette looks at different aspects of their work, with a Welsh language version following the spoken English version.

Next to the Apothecary’s Hall is an exhibition about how plants have been used to treat illnesses across the world.

Here, you’ll also find out about the Physicians of Myddfai, a network of legendary Welsh physicians who, between the 14th and 19th centuries, were renowned across Europe for their knowledge of herbal plants. There’s a legend that a Lady of the Lake gave them their special powers.

When you come out of the exhibition, pop over to the Apothecaries’ Garden next door where you can see many of the plants that are used to create pills and potions.
