Built up from the 13th to 16th centuries, when Tallinn – or Reval as it was known then – was a thriving member of the Hanseatic trade league, this enclosed neighbourhood of colourful, gabled houses, half-hidden courtyards and grandiose churches is, quite rightly, the city's biggest tourist draw. And the fact that it's all neatly packaged within a mostly-intact city wall and dotted with guard towers gives it an extra dose of fairytale charm. It’s small, compact, and very easily explored on foot.
