Well construction of the Cologne Cathedral started in 1248 and was halted in 1473, only to begin where it left off in 1842 and was eventually completed in 1880 - so don't give up hope ;)

The should have checked in with the Byzantians, the Hagia Sofia was finished in 6 years and remained the largest Cathedral for almost 1000 years.

In Spain the Sagrada Família cathedral has been under construction for 134 years and has another 30 to go.

And it was totally worth the little wait!
