Step inside Luminarium, a spectacular walk-through installation that fills St Osyth Summer Sounds with light, colour, and calm. Created by the world-renowned Architects of Air, this monumental inflatable structure invites visitors to slow down and explore at their own pace. Inside, winding pathways and soaring domes glow with radiant colour as daylight filters through the translucent fabric, creating an ever-changing, immersive experience. Luminarium is designed to be gentle, inclusive, and open to everyone. There’s no right route and no rush — just space to wander, look, and enjoy the atmosphere. Whether you’re visiting with family, friends, or taking a quiet moment for yourself, Luminarium offers a rare chance to experience art from the inside out. Tickets can be booked in advance or purchased on the door. If advance tickets sell out, a limited number of walk-up tickets will be available at the entrance.
