The “Where are we?” contest returns to test your knowledge of campus architecture. Through July, The Weekly Blog will post a new contest on the publication date of each printed edition of the Princeton Alumni Weekly.

Today’s image, taken by PAW art director Marianne Nelson, is more tightly cropped than our past samples, but careful observers may recognize this distinctive pattern of brick. Where are we? Post your answer on PAW’s Facebook page or e-mail it to PAW. The first correct response will earn a Princeton-themed prize. (Past winners are not eligible for the prize.)

 
Update: Rob Bernard ’88 won our prize for correctly identifying the Computer Science Building. This proved to be a difficult contest, but our follow-up clue seemed to help: One section of the bricks (not shown) includes an embedded code that translates to "P=NP?" Check below for the full image.
