VIDEO: University of Alabama oldest dorm implosion

(NBC) - It was out with the old and in with the new today at the University of Alabama as one of the oldest dorms on campus was demolished. 

It's housed more than 50-thousand women since 1968 and today students, faculty and staff bid farewell to one of the most iconic dorms at the University of Alabama, Tutwiler Hall.

The school says two-thousand holes were drilled and 675 pounds of dynamite were placed in the structural columns of the building.

And around 7 a.m., the dynamite was detonated.

It only took about 20 seconds, for the 13-story building to collapse.

Tutwiler Hall was named after Julia Tutwiler, who was known as the mother of co-education in Alabama.

Tutwiler successfully lobbied the University of Alabama Board of Trustees to allow female students to enroll at the University in 1883.
