Unfinished building is Antoni Gaudí's Sagrada Família in Barcelona, a church that has been under construction since 1882, and that is now expected to be complete in 2026. There are numerous unfinished buildings that remain partially constructed in countries around the world, some of which can be used in their incomplete state but with others remaining as a mere shell. Some projects are intentionally left with an unfinished appearance, particularly the follies of the late 16th to 18th century. Some buildings are in a cycle of near-perpetual construction, with work lasting for decades or even centuries. Antoni Gaudí's Sagrada Família in Barcelona,
Sagrada Família on the crossing and supporting structure for the main tower of Jesus Christ as well as the southern enclosure of the central nave, which will become the Glory façade. The church shares its site with the Sagrada Família Schools building, a school originally designed by Gaudí in 1909 for the children of the construction workers. Relocated in 2002 from the eastern corner of the site to the southern corner, the building now houses an exhibition. Chief architect Jordi Fauli announced in October 2015 that construction is 70 percent complete and has entered its final phase of raising six immense towers.
