Eero Saarinen designed the North Christian Church in Columbus, Indiana, completed in 1964. A tall spire reaches down to a hexagonal structure that splays horizontally as it meets the ground. Directly below the spire an, oculus skylight at this meeting place put light into the interior, with additional daylight coming in at the reveal between the wall and splayed ceiling.
This reveal is made possible by a moat surrounding the structure. The roof ends at grade level as trapezoidal steel legs suspend it above the floor. Slight colored variants in the light play off the interior's concrete ceiling.
This cast in place concrete structure was modernist Saarinen's last design. Dan Kiley designed the landscape.
