Coexist intends to create a building of worship for six different religions.

The circle, a symbol of unity, is the underlying theme to create a universally holy space. Six circles superimposed (one for each religious group) carve out tiered piazzas on the triangular site. These piazzas successively step down and finally arrive at the most public of programs, namely the auditorium and the main library. The building acts as a wall enclosing the various courtyards with the adjacent ancient Celian wall.
