The are a couple of sites of interest in Venice for anyone interested in Military History/Militaria
First is the armoury in the Doge's palace, cases full of renaissance arms and armour (no photography permitted) and an exhibition with a number of plans of various fortified towns.
The real gem is the Museo Navale Storico, the Naval History museum, filled with ship models, uniforms, etc. It's only 1.55 Euro to get in a real bargain and my wife enjoyed it as well so I got plenty of time to look at the exhibits.
The entrance has an original Maiale (pig) the two man human torpedo used to attack various anchorages used by the British navy in the Mediterranean.
A couple of nice Galleys
The Doge's barge, burnt by the French when they occupied Venice
Some nice figures, I need to look them up in my reference books
A WW2 Italian landing craft.
The Vitoria Veneto
A far eastern collection includes a Korean Turtle ship
A Thai barge
Outside is an enterance to the Arsenal, shame it's not open to the public as it's still a Military dockyard
