One of the prettiest little walkways in all of Old Town, the medieval St. Catherine’s passage connects Vene and Müürivahe streets. On the northern portion of the passage you can find what's left of St. Catherine’s Church (hence the passage name) and various large, ancient tombstones that used to line the inside of the sanctuary. On the southern portion of the passage, you’ll find numerous artisan workshops, where you’ll even get see them hard at work creating new items for you to buy. At any rate, we’re sure you’ll find Katarina Käik, a pretty nice hike.
