Action of 12 July 1564

German submarine U-612 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II. She was ordered on 15 August 1940 and laid down at Blohm & Voss, Hamburg, on 21 April 1941. She was launched on 9 January 1942 and commissioned 5 March 1942Oberleutnant zur See Paul Siegmann was her first commanding officer. He was joined in May 1942 by Herbert Werner, author of the book Iron Coffins, as First Officer.While still on trials in the Baltic U-612 was sunk in collision with U-444 on 6 August 1942. She was later salvaged and served as a training boat until the end of the war, when she was scuttled on 1 May 1945.

German submarine U-3519 was a Type XXI U-boat of Nazi Germany's Kriegsmarine during World War II. The Elektroboote submarine was laid down on 19 September 1944 at the Schichau-Werke yard at Danzig, launched on 23 November 1944, and commissioned on 6 January 1945 under the command of Kapitänleutnant Richard von Harpe.U-3519 was a brand new, high technology electric boat which could run constantly submerged rather than having to surface to recharge her batteries every day the way submarines until that point had had to do. However, these advanced vessels were introduced to the Kriegsmarine only late in 1944, much too late to influence the Battle of the Atlantic, and too late for many of them to serve in an offensive capacity at all. With the end of the war near, training on U-boats had dropped to a minimum due to lack of fuel, falling morale and the effectiveness of allied attacks on U-boat construction and preparation. The exception to this were the new Type XXI boats, which continued to train in the Baltic Sea. To prevent this, the Royal Air Force dropped thousands of sea mines into German territorial waters, in the hope that submarines entering or leaving harbour or training in shallow waters would be lost on them. This is what destroyed U-3519 on 2 March 1945, when she ran afoul of an air-dropped mine near Warnemünde, in position 54°11′N 12°05′E and sank to the bottom taking all 65 of her crew with her.

Warnemünde Lighthouse is a lighthouse situated on the Unterwarnow, the estuary of the Warnow river, in Warnemünde, a district in the city of Rostock. The lighthouse has a height of 36.9 metres (121 ft) and was put into service in 1898.

Warnemünde Church is a neogothic building in Warnemünde, which is a part of the hanseatic city of Rostock. Construction of the current brick building began in 1866 and the church was consecrated in 1871. The church of Warnemünde stands for over one hundred years in the middle of the town and is the center of the Evangelical Lutheran congregation. For the community along with many guests it is a place of rest and prayer. But it has also even given protection from flooding. The maritime atmosphere is shown by the special votive ships inside.

The Hanseatic University (HU) in Rostock-Warnemünde was a private university in Rostock, Germany. Founded in 2007, it was the second private institution of higher education in Germany to be granted university status by the government. In August 2008, when it had three students, it ceased activities, and it finally closed down March 2009.

Warnemünde station is located in the seaside resort of Warnemünde, a district of the Hanseatic city of Rostock in the German state of Mecklenburg-Vorpommern. The station opened on 30 September 1903 and is located on the Neustrelitz–Warnemünde railway. It is the terminus of all three Rostock S-Bahn lines. In addition, some long-distance trains serve the station. Until 1995, it was the starting point of ferries to Gedser in Denmark. The station building and some other facilities of the station have heritage protection.

The Warnow (German pronunciation: [ˈvaʁno]) is a river in the state of Mecklenburg-Vorpommern in Germany. It flows into the Baltic Sea near the town of Rostock, in its borough Warnemünde. The source of the Warnow is in Grebbin, a small village 10 kilometres (6 mi) north of Parchim, at the western end of the Mecklenburg Lake District. It flows north through Sternberg, Bützow and Schwaan before reaching Rostock. In 2003, Germany's first modern toll road, the Warnow Tunnel was opened, connecting the port of Rostock on the east bank with the west bank of the river. There is in Indaial, a city of Brazil, a river with the same name. When Hermann Blumenau came to America and started to explore the country, he gave this name to the river in the Brazilian city because it resembled the river in Germany.

Warnemünde (German pronunciation: [vaʁnəˈmʏndə] , literally Mouth of the Warnow) is a seaside resort and a district of the city of Rostock in Mecklenburg, Germany. It is located on the Baltic Sea and, as the name implies, at the estuary of the river Warnow. Warnemünde is one of the world's busiest cruise ports.

From August 22 to August 24, 1992 violent xenophobic riots took place in the Lichtenhagen district of Rostock, Germany; these were the worst mob attacks against migrants in postwar Germany. Stones and petrol bombs were thrown at an apartment block where asylum seekers lived. At the height of the riots, several hundred militant right-wing extremists were involved, and about 3,000 neighbourhood onlookers stood by, applauding them.The initial response of authorities and politicians was heavily criticised. For some days prior to the riots, veiled warnings of impending trouble had been posted in some newspapers. Police and politicians seemed reluctant to respond, and, when they did, their responses were considered inadequate. Outside the building where the refugees were housed, several hundred asylum seekers had been camping for days with little or no access to basic facilities. This was contributing to escalating tensions in the neighbourhood. Between 22 and 26 August 1992, there were 370 provisional arrests and 408 preliminary investigations related to the riots. Among the arrested were 110 people from the former West Germany; 217 from the state of Mecklenburg-Vorpommern, including 147 from Rostock; and another 37 from the former East Germany. During the riot, 204 police officers were injured. No one was killed.

The Frieden (known in German as the Traditionsschiff Typ Frieden) is the former German motor vessel Dresden operated by the VEB Deutsche Seereederei Rostock. Since 1970 it has been used as a museum ship. The Dresden was built in 1956/57 at the Warnow Shipyard. It was the fifth Type IV ship in the first batch of 10,000 tonne piece-goods freighters that were built in East Germany's shipyards after the Second World War. Because the first ship of this series was christened Frieden (commissioned in June 1957), the other ships of this series of 15 new vessels were classed as Frieden type merchant ships. On 27 July 1958 the ship was handed over to the Deutsche Seereederei shipping line and it operated until 1969 on scheduled services to East Asia, Indonesia, Africa, India and Latin America. After some serious defects that were found in the engine room that would have resulted in excessive repair costs, the ship was decommissioned in 1969 and opened on 13 June 1970 as the "Rostock Shipbuilding Museum" (Schiffbaumuseum Rostock). Part of the ship also acted as a youth hostel for a time. Today it is part of the Rostock Shipbuilding and Shipping Museum (Rostocker Schiffbau- und Schifffahrtsmuseum) in the IGA Park and contains comprehensive exhibitions of shipbuilding history. Topics include Shipbuilding in East Germany, Shipyard Operations, the History of Maritime Radio Communications and Navigation. In addition, there is a collection of various types of ship engine. Many areas of the ship have been preserved in their original state (the engine room, bridge, radio station, ship's hospital and crew cabins) and give an impression of life on a merchant ship in the 1950/60s. The Rostock City Harbour Museum Ship action group (Traditionsschiff Stadthafen Rostock) is advocating moving the shipyard and shipping museum to a central and easily accessible site in the centre of Rostock. Low visitor numbers have been cited as the reason for this initiative.

The Breitling is a roughly 2,500 metre wide bodden-like opening in the lower Warnow just before its mouth on the Baltic Sea in Germany. Its north to south extent is about 1,500 metres. The Breitling is only linked to the Baltic itself through a narrow access channel in Warnemünde, the Seekanal . For these reasons the Breitling is a perfect natural harbour. On the Baltic side the Breitling is bordered by the Rostock quarter of Hohe Düne. On its southern shore is Rostock Harbour, on the northern shore the port of the German Navy. This is where their corvette squadron and the 7th Fast Patrol Boat squadron is based. In front of Hohe Düne, separated only by the Pinnengraben ditch, lies the uninhabited island of Pagenwerder which has been artificially enlarged by dredging. The island is a protected area and bird nesting site. On the eastern shore, the edge of the Rostock Heath is the historic tourist restaurant of Schnatermann with a small sports boat harbour. In the 1950/60s there were plans for the Breitling was to be linked via the Coast Canal with the Stettin Lagoon. This project was only partly realised, however, due to high costs. In autumn 2005 the first offshore wind generator in Germany was built in the Breitling. The wind turbine was erected by the firm of Nordex, based in Rostock, and went into operation in 2006. Include the rotor it measures 90 metres in diameter, is 125 metres high and has a nominal rating of 2.5 Megawatts.

The Warnow Tunnel (also known as the Warnow River Crossing and the Warnowquerung in German) is a road tunnel 790 m long which connects the east and west bank of the Warnow river in the Hanseatic city of Rostock in Mecklenburg-Vorpommern, Germany.
