Basilica di Santa Prassede

Santa Prassede is a 9th-century church that houses Rome's most spectacular Byzantine mosaics, concentrated in the tiny Chapel of San Zeno. The gold-background mosaics here genuinely rival Ravenna's famous works - Christ Pantocrator gazes down from the vault while saints parade along the walls in luminous detail. You'll also see the column where Christ was supposedly flogged, brought from Jerusalem, and medieval floor mosaics that most visitors walk right over.

The church feels refreshingly intimate after visiting Rome's grand basilicas. The main nave is understated, almost plain, which makes discovering the Chapel of San Zeno feel like finding treasure. The chapel itself is barely large enough for six people - you'll crane your neck studying every inch of the glittering ceiling while €1 coins tick down the lighting timer. The mosaics seem to pulse with life as the artificial lighting catches different gold tesserae.

Most guides call this a "under-the-radar spot" but it's not really hidden - it's just overlooked because tourists rush past chasing bigger names. The chapel gets cramped with even three visitors, so time your visit carefully. Skip the main church entirely if you're pressed for time and head straight to San Zeno. The €1 lighting fee adds up if you want to study details properly - budget €3-4 to really appreciate what you're seeing.
