Construction on the Basílica de la Sagrada Família began in 1882 and was less than a quarter complete when its architect passed away in 1926. [1]

It remains a work in progress today.
That goes for all cathedrals though. Just two random examples, Notre Dame took about 100 years for the main structure, Cologne Cathedral took 600 years.

And is usually a matter of funding, famously Hagia Sophia was built in five years
Crazy Horse Memorial has been dragging out too. Got the impression that what exists now is functional enough to serve as a tourist trap so there's less incentive to complete it.
