The skyline of Tulsa is marked by the copper roof of the Mid-Continent building. The building was originally only sixteen stories when built in 1918 but an additional twenty stories in 1984. It’s modern gothic style stands out in the Art Deco District of Tulsa. Both styles use marble and gold for awe inspiring effects but the gothic style of the Mid-Continent building is less influenced by Egyptian style despite its ziggurat reminiscent roof . There is a lot of marble in the building but there is also a lot of cut stone and stained glass that look like a tiffany lamp  . To sustain continuity of the original Tudor-Gothic design, more than 85,000 pieces of terra cotta panels, spires, cornices and moldings were produced for the exterior façade when the building was expanded in the 1980’s.
