The Diamond & 17th Corridor is an odd little place.
Tucked between two buildings on the north side of 17th Street, it appears
to be a public corridor leading from 17th to States Street. The corridor
consists of several short staircases and long stretches of sidewalk lined
with at least four separate buildings.
The corridor travels about 60 feet before dividing to
the left and right. Turning right leads you to several private balconies
just below States Street. Turning left takes you around the side
of a building and up a staircase to another wooden platform where access
is blocked by a privately owned gate.
It is unclear whether or not this corridor was once a
public thoroughfare now blocked by private property or if it serves only
as access to the buildings in the rear of those on 17th. In either
case, it's a curious place to visit.
