The castle holds a central place in Nyborg geographically, historically and culturally.

Being the seat of these meetings, Nyborg enjoyed a number of unique and special privileges, granted by the king.

Merchants from neighboring hundreds had to come to Nyborg to sell their wares, boosting the economy and traffic in the town.

In 1446, a large number of additional privileges were added, including the outlawing of harbours between the market towns on eastern Funen.

[6] The city was captured by Swedish troops during the Dano-Swedish War, following the Battle of Nyborg.

The Swedish troops sent all valuables home to Sweden and ruined much of Nyborg Castle.

The city was retaken by an allied force of Danes, Brandenburgers, Polish mercenary cavalry and Dutchmen after a bombardment by a large Dutch naval fleet led by the famous Dutch Admiral Michiel DeRuyter, who was key in the negotiations and Swedes capitulation.

DuRuyter noted in his log that the Poles were allowed to take the captured Danish wives and daughters of Nyborg as part of the plundered booty, to his utter disgust – but there was nothing he could do to prevent it.

Following the war, the king was no longer interested in living in the castle, and it was handed over to the military.

[7] After the wars and several fires and livestock plagues, the 1700s were a low period in Nyborg's history, with the population growing poorer.

Several large markets were also held yearly, and the trade and economy of the town began to grow again.

[9] There was a single Danish casualty during the battle at Nyborg Vandrehjem: Recruit Ivan Jacobsen.

[12] The fortifications, ramparts and moats surrounding Nyborg Castle stretch out along the center of the city.

Maja Lisa Engelhardt created the altar crucifix, of gilded bronze, in 2011.

The renaissance baptismal font was donated to the church in 1585 by mayor Peder Jensen Skriver.

Inside the church is a gate from 1649, built by Christian IV's smith, Caspar Fincke.

A candle globe, made by local artisan Flemming Knudsen, was added to the church in 2008.

[15][16] The church's turret clock, nicknamed "the Syrian tank" (Danish: Den syriske kampvogn) was replaced by an electric movement in 1972.

The original mechanical movement was built by Henrik Kyhl from Copenhagen, and initially created for Viborg Cathedral, who couldn't afford it.

It is located on the Copenhagen–Fredericia/Taulov Line which connects the Danish capital, Copenhagen, and the Jutland peninsula by way of the islands of Zealand and Funen.
