The 'Two Towers' shown in old WPI logos show the clock tower of Boynton Hall and the arm and hammer weathervane of the Washburn Shops. The original weathervane was stolen in October 1975 and never recovered. Boynton and Washburn were the university's first buildings, housing the classrooms and laboratories, respectively. The Two Towers symbolize Theory and Practice, which are the foundation of the university and still the approach used today. Boynton was completed in 1868 and Washburn followed shortly after that same year.
