Raeapteek (Town Hall Pharmacy)

Open since 1422, this curious little shop on Town Hall Square is in fact the oldest continuously running pharmacy in Europe.

Ten generations of the same family, the Burcharts, operated it from1581 to 1911. It was so famous in its day that the Russian tsar used to order medicines from here.

Remedies sold at the pharmacy in medieval times included snakeskin potion, mummy juice and powdered unicorn horn (for male potency). But this was also a place to buy everyday items like jam, tea, claret, gunpowder and, most importantly, marzipan. Marzipan was one of the pharmacy's best sellers, one that local legend insists was actually invented as a curative here in the 15th century.

The historic site still operates as a pharmacy today, selling modern products, but its side room houses an interesting display of 17th- to 20th-century medicinal bric-a-brac.
