On the charming Venetian island of Murano, Museo del Vetro is an exemplary glass museum in a wonderful old palace that's worth exploring if you have an interest in the art of blowing glass. It's been a museum since the mid-1800s and features both permanent and rotating exhibits.
Don't miss the spectacularly painted ceiling fresco in the large central room on the first floor that overlooks Murano's Grand Canal. It is the work of Francesco Zugno (1709 – 1789) and depicts the allegory of the Triumph of San Lorenzo Giustinian, the first patriarch of Venice.
Note Murano island is not in central Venice. You'll need to catch the vaporetto from St. Mark's Square (it's a 35 minute boat ride). While in the area, wander the quaint streets of this island known for its glass blowing history and check out the myriad of shops scattered about.
