The Memorial House of the Bulgarian Communist Party on mount Buzludzha – an unusual structure, known locally as "the Saucer" – has fallen into disrepair since the fall of the Communist regime in 1989, although it remains a popular site for graffiti artists.

Memorial House of the Bulgarian Communist Party on mount Buzludzha
Memorial House of the Bulgarian Communist Party on mount Buzludzha. The memorial house was officially opened in 1981 by the Bulgarian Communist regime to mark the centenary of the organised Socialist movements centenary - a predecessor of the Bulgarian Communist Party. The memorial house, no longer maintained by the Bulgarian government after the fall of the Communist regime in 1989, is now abandoned and vandalised. (Matthew Swiec)
