Kader at Grad Kodeljevo runs on two levels: a terrace and a bar upstairs for talking, and an intimate basement below where the techno lives.

The castle's thick curved stone walls have made it a regular home for Endemit events. Centuries of history above ground, the pulse of the floor below — the contrast does most of the work.

More than a venue: the stone corridors lead you down into the dark, and every event here feels both rooted and free.
