Many of the country's experts contributed to the work on Karlskrona's design. One of them was Erik Dahlbergh (1625 – 1703). He was both a military man and an accomplished draughtsman, which led to him receiving many important assignments, including as a royal councilor. The exhibition depicts Erik Dahlbergh's Karlskona.

From 1661 until his death, Erik Dahlbergh worked on a book about Sweden, Suecia Antiqua et Hodierna. The name means "The former and present Sweden". The book was published in 1715 and consists of 350 engravings of sights in ancient and contemporary 1600s Sweden. Most are made from Erik Dahlbergh's drawings. The exhibition shows the pictures from Suecia Antiqua et Hodierna that show Karlskrona, which Erik Dahlbergh depicted the city.
