The concrete bunkers are everywhere in Albania, with an average of 5.7 bunkers for every square kilometer. They were built during the communist regime from the 1960s to the 1980s.
By 1983 a total of 173,371 concrete bunkers had been constructed around the country.
The bunkers were abandoned following the collapse of communism in 1990. Most are now derelict, though some have been reused for a variety of purposes including residential accommodation and shelters for animals or the homeless. Some of them are destroyed from people to get and sell the iron inside them.
Now the tourists can buy a bunker as a souvenir.
In Tirana (Capital city of Albania) there is a memorial near the former secluded area of residential government, named as Blloku. It features a bunker, pillars from Spac prison (the worst one) and a Berlin wall fragment.
