The town with most evidence of the British occupation during the 18th century and formally known as Georgetown (in the honour of George III of Britain, is Es Castell.

Its birth is directly related with Sant Felip Castle (Castell de Sant Felip), a fortress located at the harbour's entry, considered the weakest strategic point during the times of invasions.

At less than three kilometres away lies the peaceful creek of San Esteve (cala de Sant Esteve) and Fort Marlborough, a place which will take us back to the 18th century.

It is the furthest town to the east of the island and, on the whole, of the Spanish territory. This offers us the opportunity of witnessing the day's first sensation: a spectacular sunrise next to the sea.

Its urban layout preserves the original cross-sectioned streets, its parade square together with the British barracks and architecture with British reminiscences featuring "boinders" and typical "guillotine" windows. Just in front of the Town Hall, characteristically painted in red, stands the Military Museum, where many details regarding its history, information about fortresses and paintings can be found.

Es Castell looks out to the sea, moreover, towards the massive Maó Harbour. Its streets lead into Cales Fonts, an old fishing quay with the purest looks of a Mediterranean postcard, where the bar terraces and restaurants together with the handicraft stalls share an idyllic marine scenery and its caves used as shops and shelters for the fishermen.
