Core attributes that define the character, architecture, and experience of Acre (Akko).
Curated architectural landmarks, sacred sanctuaries, and cultural hubs explored in deep context.
Acre is one of the most ancient continuously inhabited port settlements in the Mediterranean basin. The original Canaanite and Phoenician settlement arose at Tell el-Fukhar (Tel Akko), located 2 kilometers east of the present walled city. Thutmose III of Egypt recorded the city as 'Aak' in the 15th century BCE. During Persian rule under Artaxerxes II, Acre served as the primary staging naval base for the Persian invasion of Egypt.
Following Alexander the Great's conquest in 332 BCE, the city was relocated to the coastal peninsula and renamed Ptolemais by Ptolemy II Philadelphus. Under the Roman Empire, Emperor Claudius established it as the military colony of Colonia Claudia Felix Ptolemais, where Julius Caesar and Roman legions disembarked during Judean campaigns. In 638 CE, Muslim armies under Caliph Umar captured the port, which was fortified under Umayyad and Abbasid rule.
The First Crusade captured Jerusalem in 1099, but it was King Baldwin I who captured Acre in 1104 with the vital assistance of the Genoese navy. Acre immediately became the chief maritime gateway to the Holy Land. After Saladin's victory at the Battle of Hattin in 1187, Acre fell to the Muslims, but King Richard the Lionheart of England and King Philip Augustus of France recaptured the fortress in 1191 following a brutal two-year siege during the Third Crusade.
With Jerusalem remaining in Muslim hands, Acre served as the capital of the Latin Kingdom of Jerusalem for the next century. The port was partitioned into fortified autonomous maritime quarters granted to Genoa, Venice, and Pisa, alongside massive commanderies of the Knights Templar, Knights Hospitaller, and Teutonic Knights. On May 18, 1291, Mamluk Sultan Al-Ashraf Khalil breached the walls with colossal siege engines, massacring the garrison and demolishing the city to the ground to prevent future Crusades.
For nearly five centuries following the Mamluk destruction, Acre lay as an impoverished coastal ruin known as 'Acco-Gare.' The dramatic revival occurred in the mid-18th century under Zahir al-Umar, who fortified the peninsula, and his successor, Ahmad Pasha al-Jazzar. Jezzar Pasha rebuilt the fortifications into an impregnable citadel, constructed monumental aqueducts from Kabri springs, built grand Turkish baths (Hammam al-Basha), and erected the landmark green-domed mosque.
In March 1799, Napoleon Bonaparte marched from Egypt with 13,000 veteran soldiers, seeking to conquer Acre, advance through Syria to Constantinople, and overturn the Ottoman Empire. For sixty-one days, Napoleon laid siege to Acre, launching eight separate assaults. Aided by British naval officer Sir Sidney Smith and royal French émigré engineer Antoine Le Picard de Phélippeaux, Jezzar Pasha's defenders held the ramparts. Napoleon was forced to retreat in humiliation, lamenting later on Saint Helena: 'If Acre had fallen, I would have changed the face of the world.'
Acre is an extraordinary living palimpsest where two distinct civilizations coexist directly on top of each other. When Jezzar Pasha rebuilt the city in the late 18th century, Ottoman builders did not remove the massive fallen Crusader masonry; instead, they used the collapsed vaults and halls as subterranean foundations for their own mosques, palaces, bazaars, and citadels.
As a result, walking through contemporary Acre is a three-dimensional journey through time. Above ground, you experience an authentic 18th-century Ottoman port city with narrow alleys, stone arches, green wooden shutters, and seaside minarets. Descending just a few meters beneath street level, you suddenly enter colossal 12th-century Romanesque stone vaults, dining refectories, and secret escape passages built by medieval European knights.
Acre’s Old City is home to a proud, close-knit Arab community of fishermen, artisans, and merchants. In late afternoon, young local divers gather atop the 10-meter-high stone seawalls near the lighthouse (Migdalor) to dive fearlessly into the crashing Mediterranean surf—a celebrated local spectacle of bravado and skill.
The city's daily life revolves around the water. Fishermen repair blue nylon nets on the docks, children steer small rowing skiffs, and the scent of roasting cardamom coffee blends with the salty sea air and fresh grilled fish.
Acre is universally recognized as one of the ultimate seafood and Levantine street food capitals of the Eastern Mediterranean:

Inside the subterranean Hospitaller Fortress in Acre, the Grand Refectory (Dining Hall) stands as one of the finest surviving examples of early Gothic architecture in the world. Constructed in the late 12th century, the hall measures over 450 square meters, spanned by eight massive quadripartite rib vaults resting on three colossal round stone pillars, each three meters in diameter.
The architectural transitions between Romanesque solidity and early Gothic elegance are visible in the sculpted stone corbels, which feature floral motifs and decorative human heads. Beneath the Refectory, a steep flight of stairs descends into the Crypt of St. John, an underground vaulted chamber that served as the secret emergency gathering point for the military commanders of the Knights Hospitaller during the siege of 1291.
Constructed in 1795 by Jezzar Pasha, Hammam al-Basha is one of the most lavish Ottoman bathhouses in the Levant, operating continuously for over 150 years until 1948. The complex features a series of dressing rooms, steam chambers, and massage halls surfaced in polished colored marble pavements, illuminated by natural sunlight filtering through hundreds of small glass circular skylights embedded in the stone domes.
Today, the bathhouse houses an innovative multimedia museum featuring the 'Last Bath Attendant' theatrical presentation, guiding visitors through the social rituals, diplomatic gossip, and relaxation culture of Ottoman Acre through sculpted figures, voice narration, and original brass steam pipes.
One of the most remarkable, overlooked engineering marvels of northern Israel is the historic Kabri Aqueduct, constructed between 1814 and 1815 by Ottoman governor Suleiman Pasha. Spanning fourteen kilometers across the Western Galilee plain, the elevated limestone conduit transported clean freshwater from the natural springs of Kabri into the heart of walled Acre.
The aqueduct rests on hundreds of monumental stone arches that march dramatically across the agricultural landscape near Kibbutz Lohamei HaGeta'ot. Inside Acre, the water flowed into public street fountains (Sebils) carved with ornate Ottoman calligraphic inscriptions, as well as the royal bathhouses and the cooling gardens of the Jezzar Pasha Mosque, ensuring the fortified city could withstand prolonged naval blockades without surrendering to thirst.
Built directly into the thick, vaulted stone interior of Acre's northeastern ramparts (Burj al-Kummandar), the Treasures in the Wall Museum offers an extraordinary journey into 19th-century everyday life. The museum recreates authentic Ottoman-era artisan workshops: blacksmiths, leather tanners, copper coppersmiths, pharmacists, and hat makers displaying original antique tools, kerosene lamps, Victorian gramophones, and historic brass samovars, providing tangible texture to the daily existence of the cosmopolitan Levant.
