The old customs house (“Gammel Toldbod”) in Nyborg is located at Havnegade 2 and holds historical significance for the town. Today, the building houses the “Kiropraktorhuset Gammel Toldbod” (Chiropractic Practice Old Customs House). In earlier times, the building served as a customs house. This was because Nyborg was situated on an important waterway, the Great Belt, where ships had long been required to pay tolls to Denmark. The old customs house in Nyborg, like other similar buildings in Denmark, played a crucial role in monitoring shipping traffic to prevent the smuggling of goods. The building in its current form was constructed during a period when these customs controls were of paramount importance.

Nyborg Town Hall was first built in 1586. After the great fire of 1797, it was rebuilt in 1803 and remodeled in 1862, with an additional floor added. Since then, it has been renovated several times, most recently in 1970. Even today, it remains an impressive and worth seeing building. https://www.visitnyborg.dk/nyborg/planlaeg-din-tur/raadhuset-i-nyborg-gdk914692

The sculpture "FORSAVN" by Lars Abrahamsen was erected to commemorate the 35 sailors from Nyborg who died in service during World War II. The sculpture is 5 meters high and made of aluminum that can be rotated on a circular plane. The memorial evokes a sinking ship, a giant sail, a compass with a large needle—or perhaps something else? It has four bronze plaques engraved with the names of the 35 sailors. https://www.visitnyborg.de/nyborg/reiseplanung/forsavn-gdk1114648

Nyborg Castle (Danish: Nyborg Slot, also Danehofslottet) is located in the town of Nyborg, about 29 kilometers southeast of Odense on Funen. The castle was built around 1170 by Duke Knud Prislavsen, a nephew of Valdemar the Great, for protection against the Wends. In 1282, Erik V. Glipping signed the first Danish charter (Danehof) here. Through this, the supreme court passed from the king to the Danehof, the first Danish parliament, which convened in Nyborg Castle. When Erik VII. moved to Copenhagen, the castle there became the center of royal power in Denmark until 1416. Nyborg, however, remained another royal residence. Later, the castle was used as an armory and granary. During the Count's Feud (1533–1536), the castle was conquered twice. Christian III. subsequently ensured an expansion of the castle and fortified it with a large rampart system. Christian IV. had the castle further expanded in 1607 by the Italian architect Domenicus Badiaz. During the war with Sweden (1658–1660), three-quarters of the castle was destroyed. The building material was partly reused in 1722 for the new construction of the castle in Odense. Nyborg itself remained a garrison town until 1913. After the dissolution of the garrison, the castle was reconstructed by Morgen Clemmensen from 1917–1923. Today, a museum is housed in the castle. Two half-towers and the gatehouse from Erik's time can still be visited. A wing with a large banqueting hall remains from the former royal palace. Three halls display Nyborg's history during the time of the Danehof, Queen Margarethe I, and Christian III. https://de.wikipedia.org/wiki/Schloss_Nyborg

The Church of Our Lady in Nyborg on Funen, on the west coast of the Great Belt, is a Gothic brick pseudo-basilica. It is the most important church building in the city and is used by the Danish National Church. The "Church of Our Lady" was built between 1388 and 1428 and consecrated on Pentecost 1428 by Bishop Navne Jensen Krigebusk. Its patron saint is Mary, the mother of Jesus. The oldest parts are the four western parts of the church, which were enclosed on the east side by a north-south wall in the early 14th century. Before 1428, the church was expanded to include the two easternmost parts, the present-day choir, and probably three additional chapels. At the time of the Reformation, three chapels with a shared roof were built on the south side of the church, and in the 1550s, King Christian III had a new chapel built. The church was expanded by an additional aisle in the north, running the entire length of the church. The large west tower and the small east tower were completed around 1600. Until 1870, the Church of Our Lady appeared as a five-aisled church. During the extensive renovation of 1870/1871, the outer aisles were demolished on both sides, except for the central nave bays. Dormers were built over the remaining outer bays, so that the church has since had a transept located unusually far to the west. Inside, however, the transepts continue to have the same low height as the side aisles. The church has two organs: the main organ, built in 1973, with 37 stops on three manuals and a pedal, is a work by Poul-Gerhard Andersen; the choir organ, built in 1872 by Johan Andreas Demant, is a single-manual organ with five stops. A special feature of this church is the design of its vaulted ribs, which are otherwise constructed from the usual short brick segments. These begin with square limestone corbels. Human heads – some of them grotesque – have been carved out of several of them. https://de.wikipedia.org/wiki/Vor_Frue_Kirke_(Nyborg)
