1. Palma Cathedral, also known as La Seu, is a monumental Gothic-style cathedral located in the heart of Palma de Mallorca, the capital city of the Mallorca Island in Spain. It is one of the most visited landmarks on the island and is considered to be one of the most impressive Gothic cathedrals in Europe.

The cathedral was built between the 13th and 17th centuries on the site of a former mosque. It is characterized by its imposing size, soaring Gothic nave, and grand rose window which is one of the largest in the world. The cathedral’s exterior features a mix of Gothic and Baroque styles, while its interior contains elaborate stained glass windows, dramatic vaulted ceilings, and intricate stonework.

One interesting fact about La Seu is that it has a unique feature called the \"Gaudi’s Crown,\" which is a decorative canopy over the altar designed by the famous Catalan architect Antoni Gaudi. Another notable feature is the \"Miquel Barceló’s contemporary altarpiece,\" a modern art installation that depicts the creation of the world through a series of abstract paintings and sculptures.
