Peyton Hall is home to offices for most of the department, several classrooms, meeting spaces, and an Observatory.  
171 Broadmead houses the McComas Space Physics Laboratory, offices for Space Physics, the LSST/Rubin group, and meeting spaces.

The construction taking place around Peyton Hall is the building of the new home for Environmental Studies and the School of Engineering and Applied Science on Ivy Lane across from Lewis Library, Peyton Hall, and Princeton Stadium.  At this writing, there is no pedestrian walkway between Washington Road and Peyton Hall along Ivy Lane; rather, you should approach Peyton Hall from the South.  Ivy Lane is open to pedestrians heading East from Peyton Hall (towards 171 Broadmead).  Click here for updated information about how to reach Peyton Hall.
