Ribbon Chapel by Hiroshi Nakamura

Ribbon Chapel designed by Hiroshi Nakamura, stands in a garden of a resort hotel, "Bella Vista Sakaigahama", in Onomichi, Hiroshima. The site is midway on a hill enjoying a panoramic view of the Inland Sea of Japan. The intertwining staircases, which cross paths at several points to provide support for each other, are designed to be symbolic of the unity that matrimony brings. 

The stairs are clad in vertical planks of white-painted wood, and have curving titanium zinc alloy handrests to withstand erosion from the sea breeze. The body of the marriage ceremony is conducted inside the glazed chapel, where a wooden aisle bracketed by two banks of seating leads to an altar. 

Nuptials are completed on the rooftop, where the two staircases widen and connect to unite the bride and groom who travel up separate flights. Once the vows are completed the couple can then pick one route to descend together.
