Barcelona Cathedral, also known as the Cathedral of the Holy Cross and Saint Eulalia, is a Gothic cathedral located in the Gothic Quarter of Barcelona, Spain. It is one of the most famous landmarks in the city, and a major tourist attraction.

The cathedral was constructed in the 13th century, but was not completed until the 15th century. It was built on the site of an earlier Romanesque church, and features a mix of Gothic and Baroque architectural styles. The cathedral has a nave and four aisles, with a total length of 93 meters. Its cloister is one of the largest in Spain, and is notable for its intricate Gothic tracery.

One of the highlights of the cathedral is the Chapel of the Holy Sacrament, which features a beautiful altarpiece by Bartolomé Bermejo. Another notable feature is the choir stalls, which date from the 14th and 15th centuries and are considered to be among the finest examples of Gothic woodcarving in the world.

Perhaps the most famous resident of the Barcelona Cathedral is Saint Eulalia, a patron saint of Barcelona who was martyred in the 4th century. Her body is said to be entombed in the crypt beneath the cathedral, along with the remains of other notable figures from the city's history.
