Louis Sullivan was retained by St. Vladimirs Russian Orthodox parish to design a suitable hall of worship. What he came up with was a unique approach to traditional Byzantine design. The elaborate interior comes as a surprise after one views the simple exterior. A richly ornamented altar looks out at a number of icons and paintings. With no pews, worshippers kneel and stand to hear services that are performed in both Old Slavic and English.
