The Technical University of Catalonia in Barcelona, Spain is home the one of the largest supercomputers in the world.
Back in 2004, when the university received money from the government to build the supercomputer, they had to first decide where to put it.
The Chapel was the only building on campus that could properly house the 10,240 processors and all the cooling units they required.
It came down to two choices, either put it in the University Chapel or build an entirely new building.
The chapel hadn't been used as a place of worship since the 1970's, so they decided to dedicate it to the project.
The Chapel is now more powerful than 20,000 personal computers!
