The Basílica i Temple Expiatori de la Sagrada Família, otherwise known as Sagrada Família, is a church under construction in the Eixample district of Barcelona, Catalonia, Spain. It is the largest unfinished Catholic church in the world. Designed by Catalan architect Antoni Gaudí (1852–1926), in 2005 his work on Sagrada Família was added to an existing (1984) UNESCO World Heritage Site, "Works of Antoni Gaudí". On 7 November 2010, Pope Benedict XVI consecrated the church and proclaimed it a minor basilica.

The Eixample is a district of Barcelona between the old city and what were once surrounding small towns, constructed in the 19th and early 20th centuries. Its population was 262,000 at the last census (2005).
