Dannemora Mine, Iron mine and industrial heritage site in Dannemora, Sweden

Dannemora Mine is an iron ore mine in Dannemora, about 45 km northeast of Uppsala. Its 72-metre wooden headframe, a listed building, stands over the shafts, and the medieval open pit Storrymningen lies nearby. The mine reaches a depth of 620 to 640 metres, and the surrounding area holds industrial and housing buildings from the 18th to the 20th century.

Mining at this location began in the 15th century and continued until 2015, making it one of Sweden's oldest mining operations. The ore extracted here was known for its high quality and was used internationally for manufacturing tools and weapons.

The red wooden clock tower at the mine entrance is the site's landmark, not a mining headframe. Dannemora iron held an uncontested top rank among Swedish iron in the 17th century; much went to Sheffield, where it was made into blister steel for tools, weapons and springs. The preserved buildings from the 1700s to the 1900s, including the 72-metre headframe, are listed as a Uppland building monument.

The site is located in northeastern Sweden and is accessible by car or public transportation, with the journey offering a chance to see the rural surroundings. Visitors should wear sturdy shoes, as the terrain is uneven and weather conditions vary depending on the season.

One of Sweden's first steam engines was installed here in the 18th century and fundamentally changed mining operations. This technological innovation made it possible to develop deeper shafts and extract larger quantities of ore.
