The main entrance to the Ivory Tower is a great arch at ground level,

A series of partitions close to the opening arch look as if they might once have been stalls for horses; further back there is a closed door that might once have led to a harness-room, and a stack of bicycles leaning against the wall, although in the dim light it is hard to tell which colour is which. Through the arch, a short stretch of gravel bordered by shrubs leads down into a narrow walled street — to the left, a worn path leads off around the foot of the tower and out of sight into the gardens.
