Ropewalk, Naval rope factory in Karlskrona, Sweden.

The Ropewalk (Repslagarbanan) is a two-storey building on Lindholmen island, about 300 metres long, making it Sweden's longest wooden building. Its length served to stretch rope strands during production. The structure combines heavy timber with wooden panelling, while rendered brick and granite buildings at each end house the machinery. It was also used to store hemp and raw materials.

Construction of the two-storey ropewalk began in November 1692, production started the following year and reached full capacity in 1696. After Stockholm's rope factory burnt down in 1676, Lindholmen was the country's only royal rope factory. A steam engine was bought in 1832, electricity arrived in 1928, and the last rope was produced on 30 December 1960.

The building now hosts exhibitions where visitors can watch traditional rope-making techniques demonstrated, offering direct insight into historical craft practices. The demonstrations show how workers once twisted and processed long strands by hand.

The site is best explored on foot, and you will get the best sense of the structure's length by walking from one end to the other. Visitors should know that opening times vary, so it is wise to check ahead before visiting.

This is Sweden's longest wooden building and retained its position as the country's only royal rope factory after the 1600s. This double distinction makes it a rare example of a surviving production building from its era.
