The story

Gladiolen Festival in Olen

Named for the gladiolus flowers once grown around this corner of the Campine, Olen's Gladiolen Festival is actually a volunteer-run, multi-stage music festival held every Pentecost weekend. Genres range from rock and hip-hop to pop and electronic beats, with a free Saturday street-theater program for families and all proceeds returned to local community groups.

Olen's Gladiolen Festival takes its name from the gladiolus flower fields once grown around this stretch of the Campine region; nothing about the modern event involves flowers, since it is a four-stage, all-volunteer music festival held every Pentecost weekend.

What is special

The part that makes it specific.

01

The place changes

Gladiolen Festival is run entirely by volunteers, with all proceeds channeled back to local community associations in and around Olen, a structure the festival is explicit about on its own site

02

The mystery stays covered

It began as a village party in 2000 and has grown into a four-stage event of over 18,000 visitors spanning rock, hip-hop, pop and electronic beats, while Saturday's free Boekel Boulevard adds street theater and children's entertainment aimed at families rather than festivalgoers alone

03

The city starts moving

In 2025 it won Best Small Festival at the European Festival Awards, an unusual distinction for a fully volunteer-run event
