Where it started.

The Bahnhofsviertelnacht brings stages, shops, studios and social projects together for one evening. Until then the programme came as a folded leaflet and a PDF: hard to read, hard to keep current and of little help on the street when visitors want to know what is happening round the corner.

What was built.

  • A programme as a map, not a list

    Every programme point sits at its real address. Opening the map shows at once what is happening within walking distance, filtered by four categories: stages, venues with their own programme, social projects and info points.

  • Enter once, up to date everywhere

    Behind the map there is a back office. Each programme point is maintained there once and appears straight away on the map, in the list and on the phone. If a time changes on the day, one entry is enough and every visitor sees the new state.

  • No work for the organisers

    The data maintenance was my job. The organisers delivered their programme; map, technology and changes were taken care of. Flyers, posters and stands led straight into the map by QR code, without an app or a login.

What came of it.

  • 97 points at 63 places, all on the map
  • 4,956 views before the festival and 6,103 on the day
  • 23,650 programme points tapped
  • One entry in the back office, up to date everywhere at once, no extra work for the organisers
