The main section of the Renaissance
Center consists of a central column surrounded by four outer columns. To
get from tower to tower there is a circular walkway on the second level.
Tower 400 is the tower at the Southwest corner.When you approach Tower 400
from the entrance ramp attached to the circular walkway, there is a reception
desk to your left. You register with the receptionist and then make your
way to the right where there is a security guard. The elevators are past
the security checkpoint.Take the elevator to the 21st floor. Go through
the fire doors straight down the hall. We are the first door to the left
of the next set of fire doors.
