Lazy Sunday Afternoon – Flower Power Festival

Sunday 30 August 2026 – 2.00 PM to 6.00 PM

Lazy Sunday Afternoon  The terrain around the Pompejustoren is once again transforming into a relaxed festival full of music, atmosphere and experience. Lazy Sunday Afternoon is back. Small-scale, quirky and exactly as you want it on a balmy summer day.

Let yourself be carried away to the era of flower power, freedom, and great music. With live performances by JAG and Mellow Yellow 69, it will be an afternoon full of recognition, singalongs, and musical surprises. From laid-back listening in the grass to gentle dancing in the sun.

But Lazy Sunday is more than just music. On the grounds, you'll find everything that makes this afternoon complete. Grab some fresh chips from the chip van, cool down at the vintage ice cream van, and browse the colourful hippie campers. For those who want to fully immerse themselves in the atmosphere, get your face painted or opt for a set of hippie braids. And amidst all the merriment, you'll discover unique hippie stuff.

As if that weren't enough, a special musical surprise awaits you this year. Something you won't see coming, but that will certainly stay with you. Grand, unexpected, and never before seen in Bergen op Zoom.

Lazy Sunday Afternoon is not a festival to tick off your list. It's one to be experienced. Together, in the sun, with a drink in your hand and music that stays with you.

LSA is a joint initiative of Mariëlle Heck and the Pompejus de Roovere Foundation.
