Stairwell
Stairwell with an elaborate lattice

 
The entrance annex stairwell pictured here is part of a multi-story apartment building and covered with a window on one side. The window is about 10 meters high and 6 meters wide and is made from more than 170 pieces of glass held in a steel lattice (only part of it shown here). It is nicely lined out with the stairs behind.
