The town centre is located on Trossö island. Many visitors are fascinated by the main square, where the Tourist Office can also be found. The square is located on Trossö's highest point and is unusually large for a Swedish provincial town. That's because the square occupies the surface of two city blocks rather than what is usual, one block. The Town Hall, The Concert Hall, Karl XI's statue and water tower, which is one of the country's first water towers, are also characteristic. 

The impressive churches are immediately eye-catching; Fredrikskyrkan (Fredrik's Church) and Trefaldighetskyrkan (The Holy Trinity Church), also known as the German Church and  it is still an active church room. Fredrik's Church was completed in 1744 and is built by mainly Italian models. The construction of Frederik's Church began in 1720 on the Great Square in Karlskrona, designed by Sweden's former chief architect, Tessin the Younger.

The flagship among Karlskrona’s parks. In the park there is a pavilion, with a café, outdoor terrace and a stage. It's hard to believe, but once was Hoglands park a swampy creek. Today is a lovely green oasis in the fairly compact city Karlskrona. Flower beds flaunts, the tall trees impresses, the children play on the playground and sometimes live music is being played here. The statue of King Karl XIII in Roman costume can be found here, as well as the statue Blekinge Girl and the statue The Frog, which is actually a girl. The park is named after a battle between the Russian and the Swedish fleet at the island of Hogland in the Gulf of Finland.

The Admirality Park (Amiralitetsparken) was established in the 1880s in a place where there had been a public square and a bastion. The streets Smedjegatan and Borgmästaregatan converge here, where it once planned a large admiralty palace. Twenty different species of trees are on display here, including walnut and chestnut. In the park stands the imposing bell tower, which probably dates back from 1699. It was at first a clock for the workers at the shipyard.

Take a stroll and get a sense of old times, amidst charming cottages and narrow alleys. The first dockworkers and craftsmen built their houses here, and it’s said that most of the timber came from the navy! The streets are named after types of vessels and admirals. Listen to the distinctive Karlskrona dialect, Björkholmskan! Here you can hear the stories on this "wild" and diphthong rich tongue. Enjoy the view of Saltösund and passing boats.

The residents, who lived at Björkholmen worked extensively on the naval dockyard, which took up a large part of southern Trossö and also some other islands. The Old Shipyard is currently one of Karlskrona's most prominent landmarks and the core of the World Heritage Site. The Rope-walk from the 1692 is, with its 300 meters length, one of the longest wooden buildings in Sweden. Here you will also find the remarkable Polhem Dry Dock, completed in 1724. During the summer there are regular tours available, for other times, please contact the Tourist Office.

The residents of Karlskrona gather at Kungsbron to welcome kings and other guests, as this is the true gateway to the town. The pink and white building is the residence of the county governor, and the view from here over the archipelago is enchanting. The Aurora Bastion is a part of the original wall that divided the city into a civilian and a military part. Today the Aurora Bastion is a popular concert venue. The designer, Erik Dahlberg is present here in the form of a bust.

On the island Stumholmen you will find Karlskrona’s foremost visitor attraction - The Naval Museum. The museum is an architectural masterpiece, with its 140-metre-plus structure extending right out over the water! The museum also incorporates the interesting Sloop and Longboat Shed with boat displays. The old hangars from the pioneering days of aviation and Kungshall storehouse are other interesting attractions. On Stumholmen you will also find Karlskrona's most popular beach, located 600 m from the Great Square, and a hostel in an old jail.

Several of the archipelago tours depart from the jetty at Fisktorget. The ”Fiskargumman” (Fisherman´s wife) statue by Erik Höglund is a reminder of the time when the women would row in from the islands and sell their fish to the town residents. One tip is to take a walk over the little footbridge to the island of Stakholmen. A perfect spot for a picnic, with fantastic views over Borgmästarefjärden, which is extra special at sunset. Here you will also find Pål Svensson's artwork "No wind", which opened in 2010.

43 red houses with white corners, waving flags and a bright blue sea. Where have you seen it before? Well, the most Swedish and perhaps the most widespread motive of all available here in beautiful Karlskrona - on the small island Brändaholm. Karlskrona's idyllic allotment cottage area with a unique built environment of the 1920s. Stroll along the narrow gravel paths and enjoy the gardens' flourishing splendor.

Further north, on Vämö, you will find Vämöparken, Karlskrona's own little equivalent of Stockholm's Skansen. Cottages were moved here from rural and urban areas, there are also a stage and a dance floor, mini zoo and walking paths. During the summer there is a flea market here on Saturdays. Vämö is also the island where Blekinge Hospital is located and where once Karlskrona would be defended against the land side. The Fortress Oscarsvärn has in recent years been stripped of vegetation and can be seen from the expressway to Trossö.
