There are not many examples of Egyptian Revival architecture in St. Louis, though there are some tombs in Bellefontaine that admirably represent the style. See the Frank Spiekerman Mausoleum, another excellent example of the style, in nearby Calvary Cemetery, for comparison.
Influenced by the thousands year old fascination Western Civilization has possessed for Ancient Egypt, coupled with Howard Carter’s discovery of the tomb of Tutankhamen, led to the revival of this architecture style.
Appropriately, considering Egyptian tombs are some of the most well-documented buildings, that mausolea should be influenced by their design.
The lotus columns and sphinxes are inspired by Egyptian temple architecture as seen at Luxor and other sites.
But there’s still room for stained glass windows.
