Inside the Palatine Chapel in Palermo, my youngest tilted her head back as far as it would go and just stared. Overhead, thousands of tiny pieces of gold-backed glass caught held the light, each one set by hand centuries ago. That’s the thing about a mosaic: nothing gets erased or painted over to make the next piece fit. It just gets set beside what’s already there.

Thinking back, that ceiling explained our entire time in Sicily.

Our family of five recently spent four days exploring Sicily together and within a single city block centuries of history were still on display—Arabic-inflected stonework, Norman towers, Spanish Baroque churches and a market stall selling street food with roots in medieval northern Africa. Standing in front of Palermo Cathedral, with its horseshoe arches and a Baroque dome dropped on top centuries later like an afterthought, I found myself asking an unanswerable question: Is this a church or a mosque? The honest answer is that it’s both, and neither, nor something that could only exist because nobody along the way tried to sand off what came before them.

A city built like a mosaic

Few cities have passed between as many rulers, or held onto as much of what each one left behind, as Palermo. By most historians’ count, eight distinct powers governed the city across nearly three thousand years—Phoenicians, Carthaginians, Greeks, Romans, Byzantines, Arabs, Normans and finally the Swabian dynasty that produced Frederick II. What struck me most, walking through it, wasn’t how many times control changed hands. It was how seldom the new owner tried to scrape the place clean before adding a new mark. A harbor sitting almost exactly between Europe, North Africa and the eastern Mediterranean was simply too useful to bulldoze and start over. Easier, it seems, to build onto what was already standing.

A trading outpost came first, set up by Phoenician merchants who cared more about warehouses than warfare. Carthage inherited the settlement, and then Greek sailors gave the harbor its own new label, one that translates roughly and appropriately, considering its many occupying cultures, to “port of everything.” Rome took the city by force in the middle of the third century B.C. and spent the next several hundred years paving roads and running aqueducts that nobody bothered to dig up later—why remove what works? Byzantine rule arrived next from Constantinople, bringing the golden mosaic work that would eventually cover half the ceilings in the old city. Then, in the ninth century, a wave of Arab governance turned Palermo into one of the largest and richest cities anywhere in Europe, its population swelling into the hundreds of thousands, its irrigation systems still visible today in the citrus groves outside town and along its outdoor market-laden streets, which have held the same look and feel for over a thousand years.

The Normans arrived in the 1070s with the instinct to keep the craftsmen who’d built Arab and Byzantine Palermo on the payroll, rather than them pushing out. Under King Roger II, a single royal command might be drafted three separate times—once in Arabic script, once in Greek, once in Latin—by scribes working side by side under the same roof. The Palatine Chapel, the room my daughter couldn’t stop staring at, is what that instinct produced: Byzantine gold overhead, a carved wooden ceiling built using an Islamic technique called muqarnas and a floor plan borrowed straight from Latin church design. UNESCO added the chapel and eight sister sites in Palermo, and nearby Cefalù and Monreale to its World Heritage list in 2015. 

What the mosaic asks of us

While it all echoes the past, as you walk through Palermo, none of it stays there. Whether you spend an evening at Quattro Canti, the Baroque crossroads at the city’s heart, trying to spot which building belonged to which era, eat panelle—fried chickpea fritters with roots in Arab-era cooking—from a market stall that’s been in the same family for generations, or stand inside the Cathedral of Monreale and take in the mosaics that have told the same stories for nearly a millennium, Palermo’s past shapes your present view of the fascinating city and the memories of it that you take into your future. 

The perspective I keep coming back to isn’t a single fact about Sicily. It’s what the city seems to be quietly communicating to us, block by block: that nothing has to be erased to make room for what comes next. A place, like a person, doesn’t need a clean slate to grow into something new—it needs the willingness to set the next piece down carefully beside the old ones and let them all keep catching the light in their wholly unique way.

If you’re planning a trip to Sicily, give Palermo more than a day. Eight empires took over two thousand years to set this particular mosaic, which means you need more than a cursory glance to actually see it.
