Valletta — Mediterranean fleet base where Jack Aubrey's Surprise lies
Jack Aubrey and Stephen Maturin arrive at Malta, where Jack seeks a new commission and is entangled in the naval bureaucracy and gossip of the port. The harbour is the stage for ship movements, preparations for the Red Sea voyage and the shadow of a leak that betrays British plans. Its crowded quays and fortified walls frame the novel's tension between honour and betrayal.
Grand Harbour has been Malta's principal naval anchorage since the Knights of St John fortified it in the 16th century. The British took control of Malta in 1800 and made it the key base of the Mediterranean Fleet during the Napoleonic Wars.
Grand Harbour remains a working port and cruise terminal with spectacular views of the bastions. Harbour ferry and boat tours let visitors see the fortifications from the water.

Valletta — Terrace overlooking the harbour
The elevated terraces of Valletta serve as the kind of vantage and meeting place where naval officers, officials and their ladies promenade. Conversations here carry the novel's undercurrents, as Stephen watches the fleet and the company for signs of the traitor in the Admiralty's confidence. The view over the anchored ships reminds characters of what is at stake.
The Upper Barrakka was created in 1661 as a private garden for Italian knights of the Order of St John. It was opened to the public in the 1800s and has long been a vantage point over Grand Harbour.
The gardens are a public park with colonnades, memorials and the daily Saluting Battery. They offer one of the best views of the harbour.

Castille Place, Valletta — Seat of authority in Malta
The seat of Malta's governing power stands for the official world that Stephen Maturin must navigate as he works as an intelligence agent. In the web of official rank and secret information, this is the kind of place where decisions about the fleet and its missions are discussed. It represents the establishment among whose circles the betrayal festers.
Built in the 1570s for the Knights of the Langue of Castile, it was remodelled in the 18th century in baroque style. Under the British it served as military headquarters.
It houses the office of the Prime Minister of Malta and is not open to the public inside. The façade can be viewed from the square.
Triq San Gwann, Valletta — Baroque church of the Knights
The grand church epitomises the Catholic and Hospitaller heritage of Malta that colours the setting. Stephen, a Catholic Catalan-Irish physician, would feel at home among its splendours, in contrast with Jack's Protestant naval world. It is a place of reflection amid the machinations of the plot.
Built between 1573 and 1577 by Glormu Cassar for the Knights of St John. Its interior was richly decorated in the 17th century, including Caravaggio's Beheading of Saint John.
The co-cathedral is a major museum and place of worship. Visitors can see Caravaggio's masterpiece and the ornate marble floors.

Old Theatre Street, Valletta — Social heart of the garrison
Valletta's social life of concerts and theatre gives the setting for Jack and Stephen's encounters with the officers, wives and officials of Malta. Such society, with its gossip, flirtations and rivalries, is where Stephen's watchfulness and Jack's pleasure in music find outlet. It evokes the cultured world around the naval community.
Built in 1731 under Grand Master António Manoel de Vilhena, it is among the oldest working theatres in Europe. It hosted performances throughout the British period.
It remains a working theatre with concerts, opera and drama, and offers guided tours.

Valletta — Fortress at the harbour mouth
The fortress guards the harbour entrance through which the ships of Jack's squadron pass. Its guns and garrison symbolise the military might of British Malta, against which the covert threat of treason is measured. Characters passing in and out of the harbour pass beneath its walls.
Built in 1552 and famed for its defence during the Great Siege of 1565. It was strengthened by the British and used as a military post.
Fort St Elmo houses the National War Museum and is open to visitors.

Valletta — Hospital of the Knights
As a physician, Stephen Maturin would take professional interest in the great hospital of the Knights and the medical world of Malta. Medicine and natural philosophy are his cover and his true passion, and such institutions link him to the island's learned society. It reflects his dual life as healer and spy.
Built in 1574, the Sacra Infermeria was one of Europe's most renowned hospitals, with a very long ward. It served as a hospital under the British until the 20th century.
It is now the Mediterranean Conference Centre, with a small exhibition on its history.

Lascaris Ditch, Valletta — Tunnels beneath the bastions
The hidden intelligence work of Stephen Maturin, with its codes, informants and secret dispatches, finds a modern echo in this underground complex. In the novel the leak of naval intentions drives the plot, and Stephen's hunt for the traitor is carried out in the shadows of official Malta. The tunnels stand for that hidden world.
The tunnels were cut into the rock beneath Valletta's bastions and used in World War II as the Allied command centre for the defence of Malta. The site is much later than the novel's era but lies within the fortifications of the period.
The complex is a museum with preserved operations rooms.

Kalkara — Bastion across the harbour
Across the water from Valletta, the fortifications form part of the harbour defences through which Surprise and other vessels move. They provide the backdrop to the preparations of the squadron and the comings and goings of boats. The fortified harbour reinforces the sense of a closed, watched world where secrets are hard to keep.
Built by the Knights of St John in the 1670s at the harbour entrance. It was used by the British as a garrison and later as a naval and military site.
The fort is largely derelict and used as a film location; access is limited.
Across Grand Harbour — Dockyard and naval quarter
The old dockyard town of Birgu, opposite Valletta, is the kind of place where ships are victualled and repaired and sailors go ashore. Jack's concern for his ship and crew takes him through such naval quarters. The dockyard setting grounds the novel's attention to practical seamanship.
Birgu was the first base of the Knights of St John after 1530 and the centre of resistance in the Great Siege. The British Royal Navy later developed the dockyard there.
Birgu has a marina, the Malta Maritime Museum in the old naval bakery and narrow historic streets.
