The Katahira Campus, the original site of the Tohoku Imperial University, was founded in 1907; and as the main campus, it concentrated in many faculties and institutions up to about 1965.
Since the Department of Engineering and others moved out to the Aobayama and Kawauchi Campus; the Institute for Materials Research, Research Institute of Electrical Communication, and others within the campus have been improved in global excellence as the Administrative Center of the university.
The Department of Science, the Chemistry Rooms of Tohoku Imperial University (built in 1927), was reconstructed recently as the University Headquarters Building, and the Department of Engineering, the Material Engineering Rooms of Tohoku Imperial University (built in 1924) , was reconstructed recently as the WPI-AIMR Main Building.
In addition, the North Gate (the main entrance of Katahira Campus) was reformed as entrance of "open-door" campus.　

Only few numbers of Early Architectures remain due to war damage in Sendai city, about 17 buildings, half of which are concentrated in the Katahira Campus. Buildings which are wooden, bricked with scratched tile, form the roundness, and soft impression of the orderly pillars with immense impression, etc. Today, the Early Architecture gives way to images of those various eras.
When you set foot on campus, you are surrounded by this unique atmosphere, and begin to experience the "Academic City" Sendai which is produced by these architectures.
Civic groups are positively acting to use, leave and preserve these Early Architectures for the next generation. And after many events, activities and evaluations, the "9th Cityscape Grand Prize" of Sendai City was awarded to Katahira Campus in 2004, and "Toshi Keikan Taisyo Tokubetsu syo 2017" (Urban townscape prize) was awarded to Katahira Campus in 2017 for its Rich Green and Early Architecture.
