The Gothic Revival Church of St. Nicholas was formerly one of the five Lutheran Hauptkirchen (main churches) in the city of Hamburg. The church lies now in ruins, with only its tower remaining, serving as a memorial and an important architectural landmark. The church was the tallest building in the world from 1874 to 1876 and is still the second-tallest structure in Hamburg.
With the founding of the Nikolai settlement and a harbor on the Alster in the 12th century, a chapel dedicated to Saint Nicholas, patron saint of sailors, was erected. This wood building was the second church in Hamburg, after St. Mary's Cathedral.
In 1335, some years before the onslaught of the Black Death, construction on a new brick building began. The structure was to be a three-naved hall church in the typical North German Brick Gothic style. This building stood until the middle of the 19th century, undergoing changes, expansions, and withstanding several partial destructions. The tower, which was erected in 1517, burned down in 1589. The tower built to replace it collapsed in 1644. The last tower of the old Church of St. Nicholas was designed by Peter Marquardt. The Marquardt tower had a height of 122 metres and with its characteristic dome was a landmark of the city and jewel of its skyline.
The old Church of St. Nicholas was the first large public building to burn in the great fire of May 1842. Shortly after the fire, the church was rebuilt again. The English architect George Gilbert Scott, who was an expert in the restoration of medieval churches and an advocate of the gothic architectural style, was commissioned to devise a new design. The architecture was strongly influenced by French and English gothic styles, though the pointed spire is typically German. The amount of sculptures made from sandstone in the interior and on the tower was unusual. The new church was built to the southeast, a short distance from the old location, where the Neue Burg had once stood. The construction started in 1846, and on 27 September 1863 the church was consecrated.
The clearly visible tower of the Church of St. Nicholas served as a goal and orientation marker for the pilots of the Allied Air Forces during the extensive air raids on Hamburg. On 28 July 1943 the church was heavily damaged by aerial bombs. The roof collapsed and the interior of the nave suffered heavy damage. The walls began to show cracks, yet neither they nor the tower collapsed.
The current condition of the Church of St. Nicholas is the result of the bombing of Hamburg in World War II, resultant demolition in 1951 and restoration work in the 1990s and 2012.
The Château du Haut-Koenigsbourg is situated in a strategic area on a rocky spur overlooking the Upper Rhine Plain, it was used by successive powers from the Middle Ages until the Thirty Years' War when it was abandoned. From 1900 to 1908 it was rebuilt at the behest of the German kaiser Wilhelm II. Today it is a major tourist site, attracting more than 500,000 visitors a year.
The first records of a castle built by the Hohenstaufens date back to 1147. The fortress changed its name to Koenigsburg (royal castle) around 1157. The castle was handed over to the Tiersteins by the Habsburgs following its destruction in 1462. They rebuilt and enlarged it, installing a defensive system designed to withstand artillery fire.
The fortification work accomplished over the 15th century did not suffice to keep the Swedish artillery at bay during the Thirty Years War, and the defences were overrun.
