The Raeapteek is one of the oldest continuously operating pharmacies in the world — the building on Town Hall Square has functioned as a pharmacy since at least 1422, and possibly earlier. It still operates today as a working pharmacy, though the interior has been restored to evoke the historical atmosphere, with wooden cabinetry, old measuring instruments, and displays of historical remedies.
It is a brief but fascinating stop on Town Hall Square — the juxtaposition of medieval trade traditions and modern pharmaceutical products in the same space is genuinely striking. The pharmacists are used to curious visitors.
