Lazise is a small walled town on the eastern shore of Lake Garda. It was once the Venetians' most important outpost on the lake — a naval base and customs checkpoint — and the medieval fortifications still stand in remarkably good shape.
The main sights are the Castello Scaligero and the Dogana Veneta at the harbour edge, a rare surviving example of Venetian administrative architecture outside Venice itself. The town walls are well-preserved and pleasant to walk along. The small Romanesque Chiesa di San Nicolò at the old port has medieval frescoes and an atmospheric setting between the water and the castle walls.
Lazise is an easy-going place to eat and drink. Local bars pour wines from the Bardolino DOC, which begins practically at the town limits, and it's easy to find a table with lake views and a plate of salami to go with a glass.
