✦ ArchUp Analysis

Marking a 25-year milestone, Days of Oris stands as a cultural and intellectual landmark in the architectural landscape of Europe. Unlike many academic conferences or commercial design expos, this event masterfully blends scholarly depth with creative energy, all in an inviting, celebratory atmosphere.

This year’s lineup is particularly impressive — drawing from a broad geographical and philosophical range. From the minimalist poetics of Kazuyo Sejima, to the regionally rooted modernism of Bevk Perović, the festival promises a rich dialogue that bridges continents and generations.
For emerging architects, it’s more than just an event — it’s a rite of passage.
