A monumental statue of Lenin gazed down at me from an archway, while an artistic depiction of Karl Marx and Friedrich Engels (the two philosophers who developed Marxism) stared vacantly towards Stalin's monstrously oversized boots. Music from Hungary's communist era played from an old jukebox by the ticket booth; a polished Trabant (a popular but compact East German vehicle known as the "people's car") was surrounded by selfie-taking tourists; while coffee mugs and posters plastered with Lenin's likeness were on sale in the gift shop.
