Red Urbex: Ghost Buildings of the Eastern Bloc

The Russian military base at Wunsdorf near Berlin was abandoned after the Berlin Wall fell. When the Soviet soldiers returned to Russia, they left behind a ghost town of the Cold War era.

This masterpiece of brutalist architecture was built in 1981 in the middle of the Bulgarian mountains under the leadership of Todor Jivkov. It was a near-sacred place during the era of Bulgarian communism, but now it's fallen into near-ruin.

It now stands forgotten on a Croatian mountain, but this steel monument that took 7 years to build was to remember the uprising of the people against fascism in the former Yugoslavia.

Tskaltubo, Georgia, is now a shadow of what it once was; one of the most popular Soviet spas. Stalin enjoyed coming here. But now, it's fallen into disuse and disrepair. These ruins blend classic Stalinist architecture with Georgian ethnic motifs. A haunting, melancoly trip through a piece of history that's fast disappearing.

In Tirana, the monument was erected in 1988 in honour of the Albanian dictator Enver Hoxha. Now, it's an empty mausoleum. After the fall of the regime, the statues were broken, and the building looted.

Inaugurated in 1981 by the Soviet authorities, the circus of Chisinau was designed as a braided basket of concrete. It's become an iconic building in the heart of the Moldavian capital.

Nicknamed the "corn cob" for its circular shape, this brutalist Moldovan tower was built in 1986 to provide temporary accommodation. It was supposed to last a hundred years but it's already decaying. People still live in this concrete rotunda which at times can feel oppressive.

This brutalist skyscraper was built in 1977 for a large Yugoslavian company, Genex. Described as "the ugliest building in the world", this incredible brutalist skyscraper is loved and hated in Belgrade in equal measure.
