The Northern Forts of Liepāja are on the edge of the Baltic Sea, and some parts of them have been washed away. This is a small, but very impressive part of the Liepāja fortifications which once encircled the entire town. The underground bunkers of the forts are on two levels, and it’s worth visiting them in the company of a knowledgeable guide from Karosta (tours are organised from the Karosta prison). There’s a car park alongside the forts. It’s also worth walking down the beach for a distance of around four kilometres to the Northern breakwater. On the shore and in the sea, you’ll see two coastal defence batteries and some pretty impressive views.
