De Vondelbunker Hidden in the Vondelpark, right under the bridge where tram 3 is riding over, you find an old fall-out shelter from the year 1947. In 1968 this space got a new destination and became Amsterdam's first youth-centre: Beatkelder Lijn 3. Fleetwood Mac, Pink Floyd and Frank Zappa played here back in the days. Today the former fall-out shelter is the residency of a new initiative called De Vondelbunker from the Schijnheilig collective, breathing new life into the monument with exhibitions, concerts, theater plays, films, discussions and other creative/activist projects.
