Baker Hall - what a historic place to work in

For the next two months, I am a visitor of Prof. Sieg at CMU. He assigned me a nice office in Baker Hall (the office number is 139B) on the ground floor. The picture shows the main entrance of Baker Hall, which is one of the oldest buildings of what used to be the Carnegie Institute of Technology. The corridors are reminiscent of train stations in the 19th century, with steel handrails and tiles.
