Almost everyone who arrives in Mahón for the first time asks the same question: why does this city not quite look like anywhere else on the Spanish Mediterranean? The answer lies in the 18th century, when Menorca spent close to a hundred years under British administration, split across three separate periods.
This was not a passing occupation. The British moved the island capital, built an entire new town from scratch, transformed the harbour and changed who held power on the island. This guide tells that story with the dates and names checked against the island's own museums, and points out what is still there when you walk through Mahón today.

A hundred years that changed the island
From the Anglo-Dutch squadron of 1708 to the dispatch that reached Mahón too late in 1802.
Why the British wanted Menorca
Menorca's position in the middle of the western Mediterranean drew the interest of every major military power of the day. British, French and Spanish forces fought over the island throughout the 18th century, through a chain of occupations. British rule was by far the longest of them, and it left the deepest mark on the island's urban development, architecture, culture and language.
The British arrived in September 1708, when an Anglo-Dutch squadron seized the island during the War of the Spanish Succession. Habsburg sovereignty was recognised at first, but the occupation soon became effective English rule. It was formalised on 14 April 1713 by the Treaty of Utrecht, under which Spain was forced to cede both the Rock of Gibraltar and the island of Menorca to England.
- September 1708: An Anglo-Dutch squadron seizes the island.
- 14 April 1713: The Treaty of Utrecht cedes Menorca and Gibraltar to England.
- The reason: A foothold in the middle of the Mediterranean with an exceptional natural harbour.
Tip: Stand at any viewpoint over Mahón harbour and you understand in about two seconds why half of Europe fought over this island.
Richard Kane and the move of the capital
The first and most notable of the British governors was Sir Richard Kane, who lived in the castle of Sant Felip at the mouth of the harbour. His name is attached to almost everything that changed on the island during those years.
His weightiest decision came in February 1722. Frustrated by the opposition he met in Ciutadella, where the nobility and the clergy were openly hostile to the British, Kane transferred the island capital to Mahón. It was a fundamental shift: the old capital turned in on itself and lived on past glories, while Mahón, far smaller at the time, began to grow quickly on the back of its harbour.
Kane is also behind the construction of a road that crossed the entire island, built so troops could be moved from one end to the other. In a Menorca of cart tracks, that was engineering on another scale.
- February 1722: Kane moves the capital from Ciutadella to Mahón.
- The real reason: Opposition from Ciutadella's nobility and clergy to British rule.
- His other great work: A road across the whole island, suitable for military manoeuvres.
Tip: The 1722 move explains a rivalry between Mahón and Ciutadella that islanders still mention with half a smile.
A harbour that filled up with people from everywhere
With the capital and the Royal Navy in Mahón, the harbour was transformed. Substantial defensive infrastructure went up and services improved, and the bustling trade attracted British, Greek and Italian merchants and shipowners. That mix is exactly why Mahón has carried the label of a cosmopolitan city ever since.
A highly lucrative maritime business also appeared: privateering. Corsairs plundered enemy ships with government authority, and in Mahón that moved serious money.
The island's population grew to 30,000, mostly peasantry and craftsmen. And in Mahón something new emerged: a bourgeoisie that grew rich on port commerce and went on to challenge Ciutadella's traditional nobility for power. The island did not just change capital, it changed hands.
- Who arrived: British, Greek and Italian merchants and shipowners.
- Privateering: Plundering enemy ships with government authority, and very profitable.
- A new class: Mahón's bourgeoisie came to challenge Ciutadella's nobility for power.
What arrived besides soldiers
The 18th century brought the Enlightenment to Menorca, and it shows in the island's politics and culture. Two names sum it up: the painter Pasqual Calbó Caldés and the Societat Maonesa, an Enlightenment body born out of that atmosphere.
One detail tends to surprise visitors: under British administration, Menorca became an exponent of the 18th-century proliferation of written Catalan, which continued to be used in public administration. The British did not interfere with religion either, preserving the continuity of Catholic worship despite differences between Anglicans and the Menorcan diocese.
It makes for an unusual military occupation, and it explains why the British mark on Menorca is felt in the urban fabric, the trade and the feel of the city rather than in any cultural rupture.
- Pasqual Calbó Caldés: The leading painter of the Menorcan Enlightenment.
- Societat Maonesa: An Enlightenment body that emerged in the Mahón of those years.
- Language: Written Catalan proliferated and stayed in public administration.
The French interlude and the town called Georgetown
On 18 April 1756, Easter Day, 12,000 French soldiers landed at Ciutadella under the Duke of Richelieu. The 300 English soldiers of the Ciutadella garrison had withdrawn towards Mahón that same day, and the old capital offered no resistance. The French crossed the island to lay siege to the castle of Sant Felip.
On 20 May the naval battle began at the mouth of Mahón harbour, between Admiral La Galissonnière's French squadron and Admiral Byng's English one. After a hard afternoon's fighting, the French won. The British besieged in Sant Felip were only 2,500 men under governor Sir William Blakeney; they held out, but signed the capitulation on 29 June. One whole town survives from that brief French spell: Sant Lluís, laid out on a straight grid across the Binifadet scrubland, with a church dedicated to King Saint Louis at its centre.
By the Peace of Paris in 1763, France returned Menorca to England. And in February 1771, during that second period of rule, the British founded a new settlement on the shore of the harbour, drawn up with an eye to the future and named Georgetown in honour of King George III. The Scottish engineer Patrick Mackellar designed it on an orthogonal grid around a central square. After the Spanish reconquest it became Villacarlos, and since 1985 it has been Es Castell.
- 18 April 1756: Richelieu lands at Ciutadella with 12,000 men.
- 29 June 1756: British capitulation at the castle of Sant Felip.
- 1763: The Peace of Paris returns Menorca to England.
- February 1771: Georgetown is founded, today Es Castell.
Tip: Sant Lluís and Es Castell are two grid-plan towns built by two enemy armies fifteen years apart. On a map they look remarkably alike.
How it ended: 1782 and 1802
On 19 August a Franco-Spanish squadron of 52 ships under the Duke of Crillón landed in the coves of Sa Mesquida and Alcaufar. The castle of Sant Felip withstood a long siege until the English surrendered on 4 February 1782.
In 1797 the island was given its own bishopric, separated from the diocese of Mallorca, with Antoni Vila i Camps as its first bishop. With it, the old rivalries between Ciutadella and Mahón resurfaced, this time over which of the two cities should host the episcopal see.
One more British period was still to come, though it lasted only from 1798 to 1802. Spain's alliance with the first French Republic under Charles IV caused the break with England and the consequent conquest of the island. In 1802, by the Treaty of Amiens, Menorca returned to Spanish hands for good. And here is the best anecdote in the whole story: as the island was being handed over, a ship appeared in Mahón harbour carrying an urgent dispatch from London ordering the British governor not to surrender it. It arrived too late.
- 4 February 1782: The English surrender at Sant Felip to the Duke of Crillón.
- 1798-1802: The third and final British period.
- 1802: The Treaty of Amiens returns Menorca to Spain.

Frequently asked questions
How long was Menorca British?+
There were three periods of British rule during the 18th century: 1708 to 1756, 1763 to 1782 and 1798 to 1802. In between came a French occupation and a few years back under the Spanish Crown. Of all the foreign dominations of that century, the British was the longest.
Why did the capital move from Ciutadella to Mahón?+
Governor Sir Richard Kane moved it in February 1722, frustrated by the opposition he met in Ciutadella, where the nobility and clergy were hostile to the British. Mahón was much smaller but growing fast thanks to its harbour, and it suited the rulers better.
Who was Richard Kane?+
The first and most notable British governor of Menorca. He lived in the castle of Sant Felip at the entrance to Mahón harbour. As well as moving the capital, he drove the construction of a road crossing the entire island, built for military manoeuvres.
What was Georgetown?+
A new town the British founded in February 1771 on the shore of Mahón harbour, named in honour of King George III. The Scottish engineer Patrick Mackellar laid it out on an orthogonal grid around a central square. After the Spanish reconquest it was renamed Villacarlos, and since 1985 it has been called Es Castell.
When did Menorca stop being British?+
In 1802, with the Treaty of Amiens, which returned the island to Spain for good. As the story goes, while the handover was under way a ship reached Mahón harbour with an urgent dispatch from London ordering the governor not to surrender the island. It came too late.
Did the British change the island's language and religion?+
No. Menorca became an exponent of the 18th-century proliferation of written Catalan, which continued to be used in public administration. And the British preserved the continuity of the Catholic religion, despite differences between Anglicans and the Menorcan diocese.
