What makes the passage particularly interesting is that it's home to the St. Catherine's Guild, a collection of craft workshops where artists use traditional methods to create and sell glassware, hats, quilts, ceramics, jewellery, hand-painted silk and other wares. The workshops are housed in the small, 15th- to 17th-century rooms on the south side of the lane, and are set up in an open-studio fashion so visitors can watch the artists at work, be it glass-blowing, weaving or pottery making.

As absorbing as these displays can be, St. Catherine's passage is more about ambience than anything else. No other place in Tallinn combines creativity with a medieval atmosphere quite like it.
