Church of Saint Martin, Split

High above the Golden Gate of Diocletian's Palace—in what used to be a narrow guard corridor—you’ll find one of Split’s smallest and most surprising sanctuaries: the Church of Saint Martin. Blink, and you might miss it. Step inside, and you’re suddenly standing in a space no larger than a hallway, transformed into a chapel sometime in the 6th century, when waves of refugees sought shelter within the palace walls. A guard post turned into a house of prayer—history does love a plot twist...

Today, the church is cared for by Dominican sisters, and for a small fee, you can squeeze in to admire its quiet treasures. The highlight is an 11th-century marble chancel screen, delicately carved with grapevines and griffins—symbols of life, faith, and perhaps a touch of medieval flair. The main altar dates back to the 9th century, proving that even the tiniest spaces can hold a very long history...

Saint Martin’s wasn’t alone up there. Similar little churches once crowned the Silver, Iron, and Bronze Gates. Where Roman niches once displayed statues of imperial tetrarchs, later generations installed saints instead—Saint Theodore guarding the West Gate, Saint Apollinaris the East, and Saint Julian the South. Empires fade; saints move in.

And then there’s the mystery. In 1929, a stone tablet was discovered in a sealed window. It read: “The unworthy servant, priest Dominic…” A gravestone, perhaps? A humble signature? No remains were ever found, so the story lingers—half fact, half whisper.

Standing underneath the Golden Gate, don’t just look forward. Look up. Because sometimes the most remarkable chapter of a 1,700-year-old palace is hiding in a space barely wider than your outstretched arms.
