May to 8 September 1565
The Great Siege of Malta, 1565, and the three places that still explain it
The Great Siege of Malta pitted an Ottoman force of some 40,000 men against around 700 Knights of St John and roughly 8,000 Maltese troops, according to VisitMalta. Fort St Elmo fell on 23 June after a month under attack, Fort St Angelo and Birgu held through the summer, and on 8 September 1565 the Ottomans withdrew. Valletta was founded the following year.

- The Great Siege of Malta ran from May to 8 September 1565.
- Some 40,000 Ottomans attacked around 700 Knights and 8,000 Maltese troops, according to VisitMalta.
- Fort St Elmo fell on 23 June; Fort St Angelo and Birgu held until the Ottomans withdrew.
- Victory led to the founding of Valletta in 1566, named after Grand Master La Valette.
I'd see it in the order it happened, Fort St Elmo in the morning and Fort St Angelo in the afternoon, crossing the Grand Harbour by ferry in between. That way you understand why the Ottomans went for the tip of the Valletta peninsula first, and why they stalled at Birgu.
Before you go
What I would keep in mind
-
01 My tip
Cross the harbour the way the defenders saw it
Heritage Malta notes that Fort St Angelo can also be reached by ferry and water taxi from Valletta, weather permitting. Seeing Fort St Elmo from the water explains the siege better than any model.

Matteo Perez d'Aleccio's Great Siege cycle hangs in the Grandmaster's Palace in Valletta. It's the winners' version of events, which is exactly why it's worth seeing.

03 To save money
Two forts and the palace on one pass
Fort St Elmo (€10), Fort St Angelo (€10) and the Grandmaster's Palace (€12) add up to €32. Heritage Malta's €60 Multisite Pass covers all three plus the rest of its sites for 30 days.

What I would book
VisitMalta quotes Voltaire saying nothing is better known than the Siege of Malta. Back home it rarely gets a mention, but on the islands it’s everywhere, in the 8 September holiday, in the palace paintings and in the name of the capital itself. Here’s what happened in 1565, using the figures the official sources give, and where the story still makes sense on the ground.
Why the Ottomans came for Malta
The Knights of St John had been in Malta for 35 years and knew how exposed they were. In 1551 an Ottoman raid carried off most of Gozo’s population into slavery, and in 1559 the Order hit back with a disastrous attack on Djerba, off the Tunisian coast. Malta had fine harbours and two forts, St Angelo in Birgu and the brand-new St Elmo at the tip of the Sciberras peninsula, where Valletta stands today.
Grand Master Jean de la Valette asked Charles V, the Pope and the Viceroy of Sicily for reinforcements. VisitMalta sums up the reply in three words. No help came. On the other side was Dragut, the corsair commanding Suleiman the Magnificent’s fleet.
The numbers, taken with a pinch of salt
In May 1565 the Ottoman fleet surrounded the islands. VisitMalta gives some 40,000 men against about 700 Knights and around 8,000 Maltese troops. Country people fled into Mdina and Birgu, burning crops and poisoning wells as they went so the invaders would find nothing.
I treat these numbers with respect but not blind faith. They’re the round figures of Malta’s official story, useful for grasping the imbalance rather than for precise arithmetic.
Fort St Elmo, the month that wrecked the plan
The Ottomans hit St Elmo first because it commanded the entrance to both harbours. Heritage Malta says it took the brunt of the attack and held out for a month, until 23 June. VisitMalta counts 36 days of assaults and 8,000 Ottoman dead to take it, and adds that Dragut was fatally wounded there.
For me, this is what decided the siege. One small fort tied down the bulk of the army for weeks the Ottomans would later badly miss. The building’s full story, including the first air raid on the islands in 1940, is in Fort St Elmo.
A summer of assaults on Fort St Angelo and Birgu
With St Elmo taken, Mustafa Pasha turned on Fort St Angelo and the fortified towns across the harbour. VisitMalta speaks of some ten attacks through the long, hot summer. On 18 August a huge part of the defences was breached and still the Ottomans couldn’t get in, with La Valette himself in the thick of it and refusing to surrender.
By September the attackers dreaded wintering on the island and morale was sinking. Then the long-awaited relief force landed at Mellieħa Bay and seized the high ground inland. The Ottoman army retreated, losing thousands more on the way out. It was 8 September, still a national holiday. Heritage Malta points out that the day marks both the end of the Great Siege and the announcement of Fascist Italy’s surrender in 1943, and, by pure chance, the Church celebrates the Nativity of Mary on the same date.
Where can you still see the Great Siege?
Three places explain it better than any book. Fort St Elmo, where the National War Museum’s gallery on the early Knights and the siege reopened on 1 August. Fort St Angelo, which the Order made its headquarters in 1530, which Heritage Malta credits with a major role in the defence. And the Grandmaster’s Palace, with the siege cycle painted by Matteo Perez d’Aleccio.
The fourth piece is the city itself. Valletta was born of the siege, founded in 1566 by the Grand Master whose name it carries, and VisitMalta says La Valette was buried there about three years later. A wander round Birgu, the town that took the summer’s assaults, closes the loop.
How I’d do it in a day
I’d start at 09:00 at Fort St Elmo, which stays open until 19:00 in summer, allowing the hour and a half Heritage Malta suggests as a minimum. Then up to the Grandmaster’s Palace, open 10:00 to 18:00, to see the paintings with the fort still fresh in mind. In the afternoon I’d cross to Birgu and give Fort St Angelo the two hours Heritage Malta recommends, with the Grand Harbour views as the light drops. If you’re going in autumn, bear in mind that all three close at 17:00 from 1 November, so the day gets shorter. What came before and after is in the history of Malta.

False. It fell on 23 June 1565 after a month under attack. The fort that never fell was Fort St Angelo in Birgu, which held until the Ottomans left.
-
Valletta already existed before the Great Siege.
See the answer
False. It was founded in 1566, the year after, on the Sciberras peninsula. UNESCO says the siege mobilised the resources to build it.
-
The relief force that ended the siege landed at Mellieħa Bay.
See the answer
True. According to VisitMalta, it appeared at Mellieħa Bay in September and took the high ground inland, and the Ottomans withdrew.

Frequently asked questions
What was the Great Siege of Malta?
The Ottoman Empire's attempt to take Malta in 1565 from the Knights of St John and the Maltese. It lasted from May until 8 September and ended with the Ottomans pulling out.
How long did the Great Siege of Malta last?
Almost four months. The Ottoman fleet arrived in May 1565 and left on 8 September. The assault on Fort St Elmo alone took a month, until it fell on 23 June.
Who won the Great Siege of Malta?
The defenders. The Ottomans took Fort St Elmo but never Fort St Angelo or Birgu, and withdrew in September when relief forces landed at Mellieħa Bay.
How many soldiers fought in the Great Siege?
VisitMalta puts the Ottoman force at some 40,000 men against about 700 Knights and around 8,000 Maltese troops. It says the Ottomans lost 8,000 men taking Fort St Elmo alone.
Why is 8 September a holiday in Malta?
It's the national day of Our Lady of Victories. Heritage Malta links it to the end of the Great Siege in 1565 and to the announcement of Italy's surrender in 1943, and it also happens to be the feast of the Nativity of Mary.
Why is Valletta called Valletta?
After Grand Master Jean de la Valette, who led the defence in 1565 and founded the city the following year, according to VisitMalta.
