The tower that was obsolete before it was finished

Godnatt is a five-sided fortress tower anchored to a tiny skerry. It was constructed between 1858 and 1862 as part of a plan to create an inner defense line for the naval base at Karlskrona. Major Adolf Lindman proposed six towers to protect the harbor, but only two were ever finished. By the time the mortar set, the design was already falling behind the rapid advancement of modern artillery.

Engineers built the tower using the old core tower style - a technique featuring thick gray stone walls and built-in casemates. This method had been common in the past, but by the mid-1800s, new rifled barrels made such stone structures vulnerable. Prince Oscar laid the last foundation stone for the structure during its construction.

Inside the tower, the layout includes a basement, two battery floors, and an open roof level. While each floor was designed to hold eight cannons, they were only armed for a very short period. In 1879, the focus shifted from warfare to navigation with the installation of a lighthouse. For a time, a lighthouse keeper lived in the upper battery floor, turning the military site into a home.

Today, the tower serves as a state-protected historic monument. It remains a visible landmark in the Karlskrona archipelago.
