Well-preserved barrels from 17th-century reveal how historic city was built

Archaeologists in Skien, Norway, have uncovered exceptionally well-preserved 17th-century oak barrels during a water and sewage renovation project in Torggata. These barrels, filled with lime and buried to prevent chemical reactivity and freezing during winter, provide valuable insights into early industrial and construction practices of the historic harbor city. The lime stored in these barrels was used repeatedly for building and rebuilding the city, revealing a clear technique employed by early construction workers. The discovery also included a wooden rammer, suggesting the site was likely a processing area rather than just a construction site. This excavation, the first major investigation in Skien since the 1970s, revealed layers dating back to the 9th century, along with medieval buildings and objects. The barrels’ remarkable preservation is attributed to the lime’s chemical properties, which also helped conserve the wood. This find has captivated locals and historians alike, highlighting how the city’s maintenance and development were closely tied to these materials and methods. Project head
