Towering Palma Cathedral (La Seu) looms large over the Mallorca seafront, built as a demonstration of the might of the Christian god for all arriving by sea. As the most prominent building in the island’s capital city of La Palma, it’s impossible to miss. Just about every city tour stops at the amazing structure and it’s also a stop on the Mallorca hop-on hop-off sightseeing bus. While impressive enough by day, the building is at its most stunning at night when the stained-glass windows are illuminated from within and floodlights shine on the sandstone façade; see it on a night walking tour of the city.
