Catedral del Buen Pastor

Catedral del Buen Pastor towers over San Sebastian with its 75-meter neo-Gothic spire, the tallest in the city. You'll find it just outside Parte Vieja in the Centro district, a five-minute walk from the old town's edge. The cathedral's most striking feature is its collection of stained glass windows that transform the interior into a kaleidoscope of colored light. Built in 1897, it's relatively young for a European cathedral but makes up for it with impressive scale and surprisingly peaceful acoustics.

Stepping inside feels like entering a different world after the lively streets outside. The soaring vaulted ceilings and stone columns create natural quiet zones where locals come to sit and reflect. The afternoon light streaming through those famous windows creates constantly shifting patterns on the floor and walls. You'll notice the church isn't packed with tourists like some European cathedrals, giving you space to actually appreciate the architecture without crowds.

Honestly, this isn't Spain's most spectacular cathedral, but it serves a purpose if you need 20 minutes of quiet between pintxos bars. The exterior is more impressive than the interior, so don't feel obligated to spend ages inside. Entry is free, which is refreshing compared to Barcelona or Seville's paid cathedral visits. Most people photograph it from the street and move on, which is probably the right call unless you're particularly drawn to neo-Gothic architecture.
