Smaller and less crowded than Pompeii, Herculaneum offers an even more intimate look into Roman life. Buried under volcanic mud in 79 AD, wooden beams, mosaics, and even upper floors survived remarkably intact. Walking through its streets feels startlingly immediate — like the residents stepped away moments ago. 

Why it’s special: Exceptional preservation and manageable size. If you want to see artifacts from the town up close in Naples, you can visit the Museo Archeologico Nazionale to see some of the best preserved discoveries.

Insider tip: Go early morning for cooler temperatures and fewer tour groups. Take a regional train from Garibaldi station near one end of Metro line 1.
