The Sagrada Familia is a large basilica located in Barcelona, Spain. It is considered one of the most important architectural works of the 20th century and is a UNESCO World Heritage Site. Designed by the Catalan architect Antoni Gaudi, the construction of the Sagrada Familia began in 1882 and continues to this day, with no set completion date.

The church is known for its highly decorative facades, which feature a mix of naturalistic and abstract forms. The Nativity Facade, which faces the east, is considered one of Gaudi's masterpieces, while the Glory Facade, facing west, was completed in 2010 and features intricate sculptures and stained glass windows.

Inside the church, visitors can admire the stunning stained glass windows, which allow light to filter into the nave and highlight the intricately carved stone columns. The central nave is topped by a magnificent starry sky, which is supported by four towering pillars.

The Sagrada Familia is one of the most popular tourist attractions in Barcelona, attracting millions of visitors each year. It is a symbol of the city and a testament to Gaudi's artistic vision and innovative approach to architecture.
