Obelisks had a prominent role in the architecture and religion of ancient Egypt.
Approximately 30 remaining ancient Egyptian obelisks are known, not including modern or pre-modern pseudo-Egyptian obelisks, such as the numerous Egyptian-style obelisks commissioned by Roman Emperors. The oldest of these extant obelisks date from the Middle Kingdom period, during the reign of Pharaoh Senusret I.
