Grimm 31

St. Catherine's Church (German: St. Katharinen) is one of the five principal Lutheran churches (Hauptkirchen) of Hamburg, Germany. The base of its spire, dating from the 13th century, is the second oldest building preserved in the city, after the lighthouse on Neuwerk island. It is situated on an island near what was formerly the southern boundary of the medieval city, opposite the historic harbour area on the Elbe river. It traditionally served as the church of the seamen.

Grimm (or The Grimm) is a former island in the Alster river at Hamburg, Germany, east of Cremon. Today there is a street in the old town, the road is probably on the island. Adolf III, Count of Schauenburg and Holstein had brought settlers from Westphalia to colonise the island. Its shore was built up after three floods from 1216 to 1219 and the island reclaimed. Up to 1300, the island was outside the city walls. In 1246 Grimm was absorbed by the city of Hamburg, and together with Cremon formed the parish of the newly built St. Catherine's Church. Grimm was untouched by the Hamburg fire of 1842 and was one of the few areas of the old city to retain its historic structure in the 20th Century. These were mainly four-storey and three-to five-axis Hamburg merchant's houses from the Baroque, with typical facades, portals and rich pre-built Ausluchten. The early 20th Century, however, saw a change in the composition of the population. The painted ceiling of Grimm 31 has been preserved in the Museum of Hamburg History since its opening in 1922.

Katharinenstraße 9, also Catharinenstraße 9, was a town house in the centre of Hamburg, Germany, built c. 1630-1640. In 1939 the house was added to the list of monuments in central Hamburg. It was not removed until 1954, 13 years after its destruction in 1941. The building was known for its stucco ceiling, commissioned between 1716 and 1720 by the building's then owner (and later mayor of Hamburg) John Anderson the Elder. The stucco was most likely by the Italian Carlo Enrico Brenno, known to have worked in Hamburg and Schleswig-Holstein. The hamburgmuseum (Hamburg History Museum) has a reconstruction of the ceiling, made from a cast of the original, which includes the original central painting, by Johann Moritz Riesenberger the Younger. The painting celebrates scholarship and art. The ceiling was restored in 2004–2005.

Cremon was a marsh island in the Alster river at Hamburg, Germany. Today the site is marked by a street of the same name, in the Altstadt of Hamburg. The island was the first of the new town, and was outside the former city walls. The land was divided into long, narrow plots, on which typical Hamburg merchant houses were built. Each plot had access to the waterway later called Nikolaifleet. Behind the houses was a waterway called the Katharinenfleet, which was filled in during 1946. The waterway separating Cremon from the neighbouring island of Grimm, the Steckelhörnfleet, was also filled in after World War II. In 1246 Cremon was absorbed by the city of Hamburg, and together with Grimm formed the parish of the newly built St. Catherine's Church. The origin of the name is unclear, it may be traced back to a local farmer. The street name has existed since at least 1251 as Cremun; a 1289, document mentions platea Crymon. In 1937, having survived the Hamburg fire of 1842 and almost one hundred years of urban development, the designation "hanseatische Traditionsinsel" was obtained. First restoration work began in 1937, but the whole street fell victim to air raids on Hamburg in 1943. Still located between Fleet Street and Cremon 33-36 (formerly outer dike), is the last of the old historic warehouse of the 18th and early 19th century.

The Afrikahaus is an office building at Große Reichenstraße 27 in the German city of Hamburg. It was built in 1899 as the headquarters of the C. Woermann firm (including the Woermann-Linie) by the Hamburg architect Martin Haller and was given listed monument status in 1972.

The New Castle (Hamburg) or Neue Burg was a medieval saxonian castle in the town of Hamburg and is the successor to the Hammaburg. In the 11th century it was the biggest castle in northern Germany and the last one built in the traditional saxonian style, only consisting of wood and earth.

The Church of St. Nicholas (German: St.-Nikolai-Kirche) was a Gothic Revival cathedral that was formerly one of the five Lutheran Hauptkirchen (main churches) in the city of Hamburg, Germany. The original chapel, a wooden building, was completed in 1195. It was replaced by a brick church in the 14th century, which was eventually destroyed by fire in 1842. The church was completely rebuilt by 1874, and was the tallest building in the world from 1874 to 1876. It was designed by the English architect George Gilbert Scott. The bombing of Hamburg in World War II destroyed the bulk of the church. The removal of the rubble left only its crypt, its site and tall-spired tower, largely hollow save for a large set of bells. These ruins continue to serve as a memorial and an important architectural landmark. When Hamburg residents mention the Nikolaikirche, it is generally to this church that they are referring, and not the new Hauptkirche dedicated to Saint Nicholas in the Harvestehude district. The remains of the old church are the second-tallest structure in Hamburg. In 2005, an elevator was installed to a 75.3-metre-high (247 ft) platform.

The Speicherstadt (German pronunciation: [ˈʃpaɪ̯çɐˌʃtat], literally: 'City of Warehouses', meaning warehouse district) in Hamburg, Germany is the largest warehouse district in the world where the buildings stand on timber-pile foundations, oak logs, in this particular case. It is located in the port of Hamburg—within the HafenCity quarter—and was built from 1883 to 1927. The district was built as a free zone to transfer goods without paying customs. As of 2009, both the district and the surrounding area are under redevelopment. As the first site in Hamburg, it was awarded the status of UNESCO World Heritage Site on 5 July 2015.

The Hamburg Stock Exchange (German: Hamburger Börse) is the oldest stock exchange in Germany. It was founded in 1558 in the Free and Hanseatic city of Hamburg.

Hamburg City Hall (German: Hamburger Rathaus, pronounced [ˈhambʊʁɡɐ ˈʁaːthaʊs]) is the seat of local government of the Free and Hanseatic City of Hamburg, Germany. It is the seat of the government of Hamburg and as such, the seat of one of Germany's 16 state parliaments. The Rathaus is located in the Altstadt quarter in the city center, at the Rathausmarkt square, and near the lake Binnenalster and the central station. Constructed from 1886 to 1897, the city hall still houses its original governmental functions with the office of the First Mayor of Hamburg and the meeting rooms for the Parliament and the Senate (the city's executive branch).
