Pompey’s Pillar, a grand 26.85-meter-high red granite column in Alexandria, Egypt, stands as a testament to Roman influence in ancient Egypt. Constructed in 297 CE to honor Emperor Diocletian, it is one of Alexandria’s few remaining Roman monuments, built on the site of the former Serapeum, a temple dedicated to the deity Serapis. Erected to commemorate Diocletian’s support during a famine, Pompey’s Pillar is surrounded by sphinx statues and ancient ruins, offering a fascinating glimpse into Alexandria’s rich Greco-Roman history.
