July 16 In Swedish History
1860: The Tamm Canal in Hälsingland is inaugurated, two years after having been finished. “Tamms kanal” has locks for steamboat traffic, which Per Adolf Tamm (1774-1856) built in order to ease the freight of iron ore from eastern Svealand via the Gulf of Bothnia to the blast furnaces by the Dellen lake system.
The route between Näsviken at Dellen and Forsa Church is 5 kilometer (3.1 miles) long. Today the lock gates at both the lock slots have been replaced with permanent dikes, but all the canal walls are still intact. In Näsviken there’s a monument of Per Adolf Tamm near the section between Dellen and the first lock.
