6 Infamous Unfinished Landmarks You Have To See To Believe

#3 Hassan Tower

The Hassan Tower, also known as Tour Hassan, is a massive minaret in Rabat, the capital of Morocco. The project, ordered by Yaqub al-Mansur in the 12th century, was supposed to be the tallest minaret in the world, and the mosque it was to be part of would have been the largest. Construction of the project came to an end, though, four years after the death of al-Mansur.
