Gaudí's unfinished basilica remains Barcelona's defining landmark and one of Europe's great architectural experiences. The exterior is extraordinary; the interior, with its filtered stained light and forest-like columns, is even better. Book timed tickets ahead.
Why It’s Worth Your Time
Gaudí's unfinished basilica, under construction since 1882, remains Barcelona's defining landmark. The interior is extraordinary — tree-form columns supporting a canopy that filters light through stained glass in colors that shift throughout the day. Book tower access (Nativity or Passion façade) for city views. Timed-entry tickets sell out days ahead in season. The building is scheduled for structural completion by 2026, Gaudí's centenary year, though finishing details will continue beyond that.
