Every April 21, the Pantheon in Rome showcases a remarkable solar phenomenon as the oculus lights up the interior at noon, coinciding with the city's birthday celebrations. This ancient architectural marvel, built during Emperor Hadrian's reign, continues to captivate visitors with its stunning design and historical significance.
In addition to this awe-inspiring spectacle, new entry fee regulations for the Pantheon will take effect in 2026, including a price hike set for July. Visitors should prepare for these changes while planning their trips to experience the Pantheon and its rich history.
