Sound Dues

Øresund or Öresund (UK: , US: ; Danish: Øresund [ˈøːɐˌsɔnˀ]; Swedish: Öresund [œːrɛˈsɵnːd]), commonly known in English as the Sound, is a strait which forms the Danish–Swedish border, separating Zealand (Denmark) from Scania (Sweden). The strait has a length of 118 kilometres (73 mi); its width varies from 4 kilometres (2.5 mi) to 28 kilometres (17 mi). The narrowest point is between Helsingør in Denmark and Helsingborg in Sweden. Øresund, along with the Great Belt, the Little Belt and the Kiel Canal, is one of four waterways that connect the Baltic Sea to the Atlantic Ocean via Kattegat, Skagerrak, and the North Sea; this makes it one of the busiest waterways in the world. The Øresund Bridge, between the Danish capital Copenhagen and the Swedish city of Malmö, inaugurated on 1 July 2000, connects a bi-national metropolitan area with close to 4 million inhabitants. The HH Ferry route, between Helsingør, Denmark and Helsingborg, Sweden, in the northern part of Øresund, is one of the world's busiest international ferry routes, with more than 70 departures from each harbour per day. Øresund is a geologically young strait that formed 8,500–8,000 years ago as a result of rising sea levels. Previously, the Ancylus Lake, a fresh-water body occupying the Baltic basin, had been connected to the sea solely via the Great Belt. The incursion of salt water via Øresund marked the beginning of the modern Baltic Sea as a salt-water body.

The Battle of the Sound was a naval engagement which took place on 8 November 1658 (29 October O.S.) during the Second Northern War, near the Sound or Øresund, just north of the Danish capital, Copenhagen. Sweden had invaded Denmark and an army under Charles X of Sweden had Copenhagen itself under siege. The Dutch fleet was sent to prevent Sweden from gaining control of both sides of the Sound and thereby controlling access to the Baltic Sea as well as of its trade. The Dutch, under the command of Lieutenant-Admiral Jacob van Wassenaer Obdam with Egbert Bartholomeusz Kortenaer as his flag captain, who had sailed to the Baltic in support of Denmark, had 41 ships with 1,413 guns while the Swedes, under Lord High Admiral Carl Gustaf Wrangel, had 45 ships with 1,838 guns. The Dutch were grouped into three squadrons, while the Swedes separated their ships into four. The seven Danish ships with about 280 guns were unable to assist their Dutch allies because of adverse northern winds and could only watch. Obdam, who initially received written instructions from the Grand Pensionary, Johan de Witt that were very complicated and confusing to Obdam. He requested the orders to be given to him again "in three words", with de Witt replying with a single sentence: "Save Copenhagen and punch in the face anyone who tries to prevent it". The "anyone" was a reference to the English, whose powerful fleet had recently defeated the Dutch in the First Anglo-Dutch War, leading to the Dutch suspecting an English fleet present might come to the aid of the Swedish, although the English simply observed the fighting from a distance, being allied to neither side. The Swedes attacked aggressively, but failed to gain the upper hand, primarily because the approaching Dutch had the weather gage. The Dutch forced the Swedish fleet to end the blockade of the Danish capital, enabling its resupply by Dutch armed transport ships, which eventually forced Charles to abandon the siege entirely. The Swedes lost five ships in the action compared to one Dutch ship, however, the remaining allied ships were more damaged. Also, considering the slightly fewer losses of men in the Swedish navy, 1,200 compared to 1,400 (439 killed, 269 captured and slightly more than 650 wounded allies), the battle is considered a tactical draw. Strategically, however, it was a major allied victory.

The Battle of Helsingborg was fought on 8 July 1362 between the Danish and Hanseatic fleets during the Danish-Hanseatic War (1361-1370).

Flakfortet, meaning sand-shoal fortress, is a sea fort located on the artificially built island of Saltholmrev, in the Øresund between Copenhagen and Saltholm. The island and fort are simply known as Flakfortet; the name of the island; Saltholmrev, meaning the reef near Saltholm, is seldom used. Flakfortet was the last of three artificial islands that the Danes created to defend the entrance to Copenhagen's harbor. (The other two are Trekroner Fort (the oldest) and Middelgrundsfortet.) Flakfortet's guns covered the Hollænderdybet channel between Middelgrundsfortet and Saltholm, and the Flinterenden channel between Sweden and Saltholm. Eventually Flakfortet became more of a site for anti-aircraft weapons than for coastal artillery. Its military functions ended in 1968. Flakfortet is currently used for recreational purposes such as concerts, and the site has a restaurant and yacht moorings. During the summer, a ferry company, Spar Shipping, has five scheduled trips per day to the island, with the trip from Nyhavn taking about 40 minutes each way. There is an overnight hostel on the island too.

Indfødsretten (Danish, lit. Citizenship) was a 64-gun ship of the line in the Royal Dano-Norwegian Navy commissioned in 1787. She was one of a class of five ships designed and constructed by naval architect Henrik Gerner.

Landskrona Water Tower (also called the New Water Tower by local name, in order distinguish it from the old water tower in the city) is a water tower located in Landskrona, Sweden.The tower has a circumference of 49 m (161 ft), is 65.9 m (216 ft) high and was completed in 1970. It replaced the old water tower which was put out of use in 1975.The tower characterizes the city's skyline with its height and position next to the sea and can easily be viewed from the Danish side of the Øresund. It has previously been open to public visits up to the top of the tower, but this was cancelled in the early 2000s due to safety issues.In 2015 there was an issue with pieces of concrete falling from the top of the tower. This was addressed in 2016 as the tower was clothed with a steel netting.

Öresundsvarvet was a Swedish shipyard in Landskrona that was established in 1915 and largely phased out between 1980 and 1982.

Sofia Albertina Church (Swedish: Sofia Albertina kyrka) is the main church in Landskrona, Sweden. Belonging to the Landskrona Parish of the Church of Sweden, it was inaugurated in 1788 and fully completed in 1816. It is considered a rare church building, in the respect that it has two towers without being a Bishop's church. The church was originally designed by Carl Hårleman, as perhaps his last greater task. Hårleman died in 1753, the same year as the old church was demolished. Smaller changes to Hårlemans original may have been done.

Landskrona City Hall is a city hall in Landskrona that hosts the central government of Landskrona Municipality. The house is located by the new harbor, near the Sofia Albertina Church and barely half a kilometer east of the Landskrona Water Tower, which is located along the city's west coast. The building, designed by Sten Samuelson and Inge Stoltz, was inaugurated in September 1976 and most recently underwent an interior renovation that was completed in 2021.

Middelgrundsfortet or Fort Middelgrund, known as Ungdomsøen (The Youth Island) since 2015, is a sea fort located on an artificial island in the Øresund between Copenhagen and Malmö. The fortress is constructed at a point where the seabed is 7 meters below the water surface, and at the northern meeting point of the straits Kongedybet and Hollænderdybet.

Ungdomsøen (The Youth Island) is a youth camp located on the artificial island of Middelgrundsfortet in the Øresund sound between Copenhagen and Malmö.

Landskrona Town Hall (Swedish: Landskrona rådhus) is a town hall located in Landskrona. The town hall was inaugurated in the year 1884 after construction had started in 1882. The historical building has been designed by the Danish architect Ove Pedersen and is primarily used for Landskrona municipal council meetings.In the same place as the current town hall was previously an older medieval town hall, which was demolished to make room for the new building. The former building had served as a town hall since the middle of the 15th century.
