It is not known exactly when the art of glass making began in Venice, except that it has been confined by law to the islands of Murano since 1291. Since then, Murano glass has been celebrated worldwide for its craftsmanship, creativity and originality. Today, some 260 glass-making companies remain in operation on the islands and are visited by millions of visitors looking to learn about the tradition of Venetian glass making. Buona visita!
