After 137 years of ongoing construction, Barcelona’s Sagrada Familia received a building permit on June 6.

Construction on the basilica is expected to be completed in 2026.

Architect Antoni Gaudí began his work on Sagrada Familia in 1883, and in 1914 stopped all other projects to work exclusively on the basilica, to which he dedicated himself until his death in 1926.

“It was a historical anomaly that La Sagrada Familia did not have a license,” said Janet Sanz, deputy mayor for Ecology, Urbanism and Mobility, according to NPR.

“They were working on the church in a very irregular way,” she said. “And we were very clear that, like everyone else, La Sagrada Familia should comply with the law.”

A permit had been applied for in 1885, but the city’s council never responded to the application. Three years ago, the authorities discovered that the building did not have the proper paper-work.
