Pierce Hall
Pierce Hall is the name given to the building that was once planned for the space in front of Mathematics Hall, completing a mirror quadrangle to Avery-Schermerhorn-Fayerweather. Need less to say it wasn't built, nor will it ever be built as the administration has stated that the Northwest Science Building will be the final building erected on the main campus. However, the administration had toyed with the idea as recently as the late 90s, as its construction was one of three proposals for building on the main campus outlined in the 1998 Framework for Planning study.
