Visitors will be thrilled to watch free of charge the traditional skills of glassblowers at work in part of an upmarket glass and gift shop of enormous elegance. Operated by Dartington Crystal Ltd., the light and airy building, on the water’s edge, is the cleverly transformed Old Fish Market, in the Barbican. Open every day, adjacent to the Mayflower Steps and opposite the National Marine Aquarium, the Glassworks is a most for all visitors to Plymouth Barbican.
