The Imperial Palace of Maximian, hidden in plain sight, is a relic of Milan's imperial ambitions, where ghosts of emperors still roam its corridors. 

This ancient palace, now partly enfolded by the modern city, was once the epicentre of Roman power in the north. Strolling through its remains, one can almost hear the clink of armor and the whisper of togas. It's a place where history buffs can geek out on archaeological finds and daydream about Milan's days of imperial grandeur, all without bumping into a single centurion.

Best time/season to visit:
While the ruins are majestic year-round, the spring and fall offer mild weather for those looking to ponder the empire's rise and fall in comfort.
