Cathedral of Santiago de Compostela

The great Romanesque cathedral at the end of the Camino de Santiago pilgrimage, said to hold the tomb of St James. Pilgrims arrive in the Praza do Obradoiro in front after walking for weeks. Inside, see the Portico of Glory, and, at some masses, the giant incense burner, the botafumeiro, swung across the church on ropes.

The rooftop tour gives views over the city. The old town is a UNESCO World Heritage Site, with stone streets and arcades. Even if you don't walk the whole Camino, you can walk the final stages.
