Visitors should park in the 550 Lone Pine Road lot and follow the sidewalk bordering the Thompson Oval (football field) to the main staircase leading to Hoey Hall. Proceed up the stairs. Enter the building on the second level via the first door on the right, and turn left. Check in with the Upper School Dean of Boys office (the second door on the right).
Named for Harry D. Hoey, the fourth headmaster of Cranbrook School, Hoey Hall is the academic hub of the Cranbrook campus, with classrooms, a library, study halls, an assembly hall, and administrative and faculty offices. The main entrance, off the Quad just south of the Tower, opens onto the large, welcoming south lobby that features a huge fireplace embellished with tiles designed by Eero Saarinen. Behind the shuttered counter at the west end of the lobby is the office of the Dean of Boys. Just north is a hallway dubbed "Senior Hall," where seniors gather between classes and after school to socialize beneath wide windows that look out onto the football field.
The two-tiered octagonal tower off the south lobby rises to a small dome that originally held the observatory and telescope that now reside in the Institute of Science. The lower-level entrance to the tower, known today as the science door, is through the Galileo portal. Here, a sandstone Galileo stands on a pedestal above representations of astronomy, invention, physics, geology, geography, and biology.
