The Secrets of Split

Where a Roman Emperor’s Palace Became a Living City

A Roman emperor built himself the grandest retirement home in history. Then he died, and ordinary people moved in. They carved homes into imperial walls, turned a mausoleum into a cathedral, and built a thriving city inside palace corridors. Split is not a city with ruins — it is a city built from ruins. For 1,700 years, life has never stopped within these walls.

The Imperial Retirement
A Palace for the Only Emperor Who Quit

In 305 AD, Diocletian became the only Roman emperor to voluntarily abdicate. He came home to this palace — and never looked back.

🏛️
Diocletian’s Palace — Bronze Gate & Cellars
Roman Empire · 293–305 AD
You enter through the Bronze Gate, the southern entrance that once opened directly onto the sea. Below your feet stretch the substructures — massive underground halls that mirrored the emperor’s private apartments above. These cellars survived because medieval residents used them as a rubbish dump, sealing and preserving them for centuries. Rediscovered in the 20th century, they are now one of the best-preserved Roman interior spaces on Earth.
🧩 Riddle
Diocletian’s Palace covers a huge area. Approximately how large is it?
💡 Need a hint?
Think of a large city block — roughly 30,000 square meters...
🎉 The Answer
B. 30,000 m²
The palace covers roughly 30,000 m² (about 215 × 180 meters) — essentially a small fortified town. Today, approximately 3,000 people still live within its walls, making it one of the most continuously inhabited ancient structures in the world.
The Heart of Power
Where Subjects Knelt Before a God-Emperor

This open courtyard was the ceremonial heart of imperial power. Ordinary people were forbidden entry — on pain of death.

The Peristyle
Roman Empire · 4th Century AD
You stand in the Peristyle — an open-air courtyard framed by granite columns brought from Egypt. This was Diocletian’s grand reception hall, where visitors would prostrate themselves before the emperor, who appeared on the raised southern platform like a living god. Today, cafes fill the ancient colonnades and opera singers perform under the open sky on summer nights.
🧩 Riddle
The Peristyle’s columns are made of granite imported from a faraway land. Where did they come from?
💡 Need a hint?
Land of pharaohs and pyramids...
🎉 The Answer
C. Egypt
The red granite columns were quarried in Egypt and shipped across the Mediterranean. In 1968, an art student painted the entire Peristyle red in a famous protest — an event now celebrated in Croatian art history.
The Sacred Transformation
The Emperor’s Tomb Became His Enemy’s Church

Diocletian persecuted Christians with unmatched cruelty. The irony of what happened to his mausoleum is extraordinary.

Cathedral of Saint Domnius
Mausoleum 305 AD · Cathedral 7th Century
This octagonal building was Diocletian’s mausoleum, built to house his body for eternity. But Christians — the very people he tried to annihilate — removed his sarcophagus, installed the bones of Saint Domnius (a bishop Diocletian had beheaded), and consecrated it as a church. The 57-meter bell tower was added starting in the 13th century and offers panoramic views of Split.
🧩 Riddle
This cathedral holds a remarkable record. What is it?
💡 Need a hint?
Think about age and continuous use on original premises...
🎉 The Answer
B. Oldest Catholic cathedral still in its original structure
The Cathedral of Saint Domnius is considered the oldest Catholic cathedral in the world still in use in its original structure, dating to the turn of the 7th century. Diocletian’s sarcophagus has never been found — it simply vanished.
Gods and Transformations
From Jupiter’s Altar to a Baptistery

Diocletian claimed descent from Jupiter. This temple honoured the king of gods — until Christians found a better use for it.

🕊️
Temple of Jupiter
Roman Empire · 295–305 AD
A headless sphinx of black granite from Egypt guards the entrance — one of the few surviving originals from Diocletian’s collection. Inside, the barrel-vaulted ceiling still bears intricate Roman carvings. Around the 6th century, the temple was converted into a baptistery dedicated to Saint John. The contrast is striking: pagan relief carvings share walls with medieval Christian crosses.
🧩 Riddle
An Egyptian sphinx guards the temple entrance. What material is it carved from?
💡 Need a hint?
A dark, heavy stone quarried in Egypt...
🎉 The Answer
C. Black granite
The sphinx is carved from black granite and is roughly 3,500 years old — older than the palace itself by over a millennium. Diocletian collected sphinxes from Egypt; originally there were perhaps a dozen, but only three survive in Split today.
Defiance in Bronze
The Bishop Who Challenged a Pope

Just beyond the grandest of the four palace gates stands a towering statue of a man who dared challenge Rome itself.

🏰
The Golden Gate & Gregory of Nin
Roman Gate 305 AD · Statue 1929
The Golden Gate (Porta Aurea) was the most ornate entrance to Diocletian’s Palace — reserved for the emperor himself. Just outside stands the 8.5-meter statue of Gregory of Nin by sculptor Ivan Meštrović (1929). Gregory was a 10th-century bishop who fought for the right to conduct mass in Croatian instead of Latin — defying the Pope. Tourists rub his left big toe for good luck, and it gleams gold from centuries of touches.
🧩 Riddle
The statue of Gregory of Nin was created by Croatia’s most famous sculptor. Who?
💡 Need a hint?
His gallery sits on Marjan Hill, and he’s considered one of the greatest sculptors of the 20th century...
🎉 The Answer
B. Ivan Meštrović
Ivan Meštrović is considered the greatest Croatian sculptor of the 20th century. The statue was originally placed in the Peristyle in 1929 but Italian occupying forces moved it in 1941. It was re-erected at the Golden Gate in 1954. The shiny golden toe is the most-rubbed body part in all of Croatia.
Medieval Expansion
Where Split Outgrew the Emperor

By the 13th century, Split’s citizens needed more room. They expanded west, beyond the palace walls, and built a new civic heart.

Narodni Trg (People’s Square)
Medieval · 13th Century Onward
This rectangular square — known as Pjaca to locals — became Split’s main public space when the medieval city expanded beyond Diocletian’s walls. The 15th-century Town Hall (now the Ethnographic Museum) anchors one side. A Romanesque clock tower marks the hours. For centuries, this was where laws were read, markets held, and justice dispensed. Today, cafes fill the square and the old clock still keeps time.
🧩 Riddle
This square has a local nickname used by all Split residents. What is it?
💡 Need a hint?
An Italian-sounding word for ‘square’ or ‘piazza’...
🎉 The Answer
B. Pjaca
Pjaca derives from the Italian ‘piazza.’ Split’s language is peppered with Italian loanwords from centuries of Venetian influence. The Ethnographic Museum inside the old Town Hall has a rooftop terrace with panoramic views of the old town’s terracotta rooftops.
The Modern Master
A Sculptor’s Villa on the Adriatic

Croatia’s greatest artist built himself a villa-studio on the slopes of Marjan Hill. It became one of Split’s finest museums.

🎨
Meštrović Gallery
Built 1931–1939
Ivan Meštrović designed this elegant neoclassical villa as both his home and workspace in the 1930s. The building itself is a work of art — colonnades, gardens, and terraces overlooking the sea. Inside: over 200 sculptures, drawings, and architectural plans spanning his career. The adjacent Kaštelet chapel houses his medieval-inspired wood carvings depicting the life of Christ.
🧩 Riddle
Meštrović is considered one of the world’s great 20th-century sculptors. Which famous institution gave him a solo exhibition in 1947?
💡 Need a hint?
A major New York City museum with ‘Metropolitan’ in its name...
🎉 The Answer
C. The Metropolitan Museum of Art
In 1947, Meštrović became one of the very few living artists to receive a solo exhibition at The Metropolitan Museum of Art in New York. He later emigrated to the USA and taught at Notre Dame University until his death in 1962.
The Gate That Never Closed
1,700 Years of Continuous Use

Of the four gates of Diocletian’s Palace, only one has been in continuous daily use since the day it was built.

The Iron Gate & Church of Our Lady of the Belfry
Roman Gate 305 AD · Church 11th Century
The Iron Gate (Porta Ferrea) is the western entrance to Diocletian’s Palace — and the only gate that has never been sealed, blocked, or fallen into disuse in 1,700 years. Above the passageway sits the tiny Church of Our Lady of the Belfry, built in the early 11th century. Its medieval bell tower — one of the oldest in Dalmatia — features a rare Romanesque relief of the Virgin Mary.
🧩 Riddle
What makes the Iron Gate unique among the four gates of Diocletian’s Palace?
💡 Need a hint?
Think about what has happened to the other three gates over the centuries...
🎉 The Answer
B. It has been in continuous use since 305 AD
The Iron Gate has been open and in use every single day since 305 AD — over 1,700 years without interruption. The other three gates were walled up at various points in history. The Romanesque clock on its outer face is one of the oldest still-functioning clocks in Europe.
The Green Escape
Split’s Lungs and Lookout

A pine-covered peninsula rising 178 meters above the sea, Marjan Hill has been Split’s refuge for centuries.

🌿
Marjan Hill
Protected Since 1964
Marjan Hill is Split’s beloved green lung — a forested peninsula where locals jog, hike, and escape the summer heat. At the Vidilica viewpoint, the entire city unfolds below: Diocletian’s Palace, the harbour, and the islands beyond. Ancient hermit caves dot the southern cliffs. The 15th-century Church of St. Nicholas sits atop the hill, watching over the city’s fishermen.
🧩 Riddle
What is the height of Marjan Hill at its peak?
💡 Need a hint?
Under 200 meters, but high enough for dramatic views...
🎉 The Answer
C. 178 meters
Marjan Hill stands 178 meters above sea level. Its pine forests were planted by citizens over centuries to prevent erosion. In 2000, the city had to fight off a massive development project that threatened the hill — Split’s residents protested and won, preserving their green sanctuary.
The Living City
Where Split Plays Picigin

This sandy beach east of the old town is the birthplace of Split’s most beloved sport — one you won’t find anywhere else.

🏖️
Bačvice Beach
Split’s Social Heart
Bačvice is not just a beach — it is a social institution. Since the early 20th century, this shallow sandy bay has been the home of picigin, a uniquely Split ball game played in ankle-deep water. Players dive and leap acrobatically to keep a small ball in the air, never letting it touch the water. There are no teams, no scoring — just style and flair. In 2005, picigin was added to Croatia’s register of intangible cultural heritage.
🧩 Riddle
Picigin is Split’s signature sport. What is the objective of the game?
💡 Need a hint?
It’s not about scoring goals or points — it’s about keeping something airborne...
🎉 The Answer
C. Keep a small ball from touching the water
Picigin was born at Bačvice around 1908 when students started batting a ball in the shallows. The game requires no equipment besides a small ball (often just a peeled tennis ball). Expert players perform spectacular dives and acrobatic saves. In 2005, it became officially protected cultural heritage of Croatia.
