I love Albania, for reasons related to my job I used to travel there multiple times a year until around 2010.

Those bunkers are absolutely everywhere, even right in the middle of nowhere (I guess that's useful if you happen to get lost in the wilderness while hiking).

In towns and cities they have been sometimes repurposed, e.g. I remember seeing that someone created a small cafe on the beach using one of the larger bunkers.

The problem with reusing them is that the vast majority of the bunkers are of the smaller type (mostly below ground level, and on the inside there is barely enough room for a couple of people) and it's hard to find a new purpose for those.
