Origin of Obelisks in the Ancient World

Obelisks have been around since ancient times. An obelisk is defined a tapering structure with four sides and a pyramid shape at the top. The word “obelisk” is Greek for a pointed pillar. Herodotus used the term to describe the tall structures he saw in his travels to Egypt. The Egyptians themselves called them “benben.”

The obelisk was a common feature of Egyptian architecture. Pairs of obelisks were placed at the front of temples. The biggest Egyptian obelisk still in the country is 20.7 meters high and weighs 120 tons. The tallest is 105.6 feet tall and located today in Rome. The ancient Romans were quite fond of the obelisk design and either built them themselves or carried off the ones they found in Egypt.

The Egyptian obelisks were originally monolithic, made from pure red granite. The pharaohs erected obelisks to commemorate the 30th anniversary of their kingship.
