The Mieczysław Karłowicz Philharmonic Hall is Szczecin's most striking modern building — a cluster of crystalline forms in white glass and steel, designed by the Barcelona-based firm Barozzi/Veiga and completed in 2014. It sits near the castle hill, and the contrast between its 21st-century geometry and the Baroque and Gothic buildings nearby is dramatic and intentional.
The building is worth seeing from the outside even if you don't attend a concert, but attending one is by far the better option. The acoustics are excellent and the programming is ambitious by any European standard — the philharmonic has a strong reputation and regularly invites international soloists. Tickets are affordable compared to equivalent venues in Berlin or Warsaw.
