An upright four-sided pillar, gradually tapering as it rises and cut off at the top in the form of a pyramid, symbol for the Egyptian god, Re, who held the power to recreate, hence, God, lord over all, creator.
Obelisks were a feature of the Egyptian Revival architectural style which reached its peak during the late 1800s. As the style was adapted by Victorian-era Christians, the obelisk came to represent rebirth and a connection between earth and heaven.
