The water tower at "Dronningens Bastion" is a unique example of contemporary industrial construction, at its best. It was declared worthy of preservation in 1997 and is unique because the sanitary facilities are largely intact. As far as is known, it is the only water tower in Denmark with a preserved water tank made of riveted steel plates. Originally, the city was supplied with drinking water from the castle lake. From here, it was led to the various water taps in the city in hollowed-out oak logs, connected by iron sleeves. Three generations of the Kjellerup family ensured for over 100 years that the system worked. During excavations in the city, you still often encounter the oak logs and a few are kept in the castle's cellar. Such a water supply was of course not very hygienic and after the cholera epidemic, the city council discussed several times the construction of an actual waterworks. The first waterworks was based on groundwater drillings and was inaugurated in 1872. It was located below the water tower and was a larger building complex. To provide enough space, part of the moat was filled with sand. However, the waterworks was demolished again and the moat has now regained its original appearance. The water tower measures 22.4 meters from the terrain to the roof peak. Measured from the inside, it is 24 meters high, for comparison, the "Rundetårn" in Copenhagen is 36 meters high. https://www.visitnyborg.de/nyborg/reiseplanung/der-wasserturm-der-dronningens-bastion-gdk761912

The Knald Station here in Knudshoved is one of the oldest surviving acoustic warning systems in the country. It was introduced in 1901 by the Lighthouse Directorate as a warning system for ferry traffic on the Great Belt, replacing the outdated acoustic warning that occurred when two cannons called "Löwes Batteri" were fired. The Knald Station was intended to guide ferries safely into Nyborg Fjord by sound in cases of dense fog, heavy snowfall, etc. In normal weather conditions, the ferries could navigate using the visual lighthouses that had guided ships safely into Nyborg Harbor since the mid-19th century using bonfires and lighthouses. But when the weather and visibility were poor, the lighthouses could not be seen. The Cracking Station was built with a 7-8 meter high mast, equipped with a curved rocker arm at the top, which could be lowered to a small shed built next to the mast. Here, the explosive charges were mounted on a gallows and the rocker arm was raised back into the air. The explosive charges were detonated using an electrical device, and the ferries could orient themselves according to the sound. The cracking station was decommissioned in 1934 and replaced by more modern warning systems (electric sirens). From 1934 onward, and for 40 years afterward, the cracking station stood and fell into disrepair. In 1976, it collapsed onto the beach due to cliff erosion. In 1983, the mast and rocker arm of the blasting machine were reconstructed, but mistakenly fitted with a firewood basket, as if it were a "rocker light" for visual warning. After restoration in 1983, the mast and rocker arm of the blasting machine were once again in poor condition and were restored to a high shine in 2009 with paint and new steel wires. In 2022, DSB Ejendomme carried out a careful restoration of the mast, tilting structure, and stiffening wires. The mast and tilting lever have now been returned to their original design and fitted with a gallows for securing the explosive charge. https://www.visitnyborg.dk/nyborg/planlaeg-din-tur/fyrtaarn-og-knaldfyr-paa-knudshoved-gdk1114413
