Constructed in 1887 entirely without iron, Skull Tomb was a place where WPI faculty members and students conducted delicate experiments in electricity and magnetism until vibrations from early Worcester streetcars ended that work.
The building was next used for experiments with high-voltage transformers. For a time, the student newspaper was published here. In 1917, rocket pioneer Robert Goddard, class of 1908, used the building for secret experiments. Since 1921, this has been the home of Skull, a senior honorary society, which holds its secret ceremonies here.
