Magelungsfortet, Military fortification in Huddinge Municipality, Sweden

Magelungsfortet is a fortification squeezed between Nynäsvägen and Gamla Nynäsvägen between western Trångsund and Skogås in Huddinge Municipality. Built in 1908, as the date on a stone tablet above the entrance shows, it stands high above Lake Magelungen and covered the right flank of the Beateberg position. It consists of an infantry line, a firing trench, and a machine-gun battery with room for five machine guns, three in the lower part and two in the higher.

Magelungsfortet was built in 1908, the year carved on a stone tablet above its entrance, as part of the Southern Front (Korvlinjen) planned around 1900 to replace central defence with a border and coastal line. Private donors organised in the Association for Stockholm's Fixed Defence and the Palmqvist Foundation paid for the works, which the military built under civilian direction and then received as a gift. The line remained in the defence organisation until 1952.

The name comes from Lake Magelungen just west of the fort. The position covered the right flank of the Beateberg pass, the largest position of the Southern Front, planned for about 3,700 soldiers, mainly Landstorm infantrymen over 32 armed with ordinary rifles. A 1909 drawing shows space for five machine guns, three in the lower part and two in the upper.

Magelungsfortet lies wedged between Nynäsvägen and Gamla Nynäsvägen, between western Trångsund and Skogås in Huddinge municipality. The site is reached from Gamla Nynäsvägen, to which a roughly 180-metre road was laid when the battery was built. The ground is uneven, so sturdy footwear helps.

A 1909 drawing shows the machine-gun battery held five guns: three in the lower section and two in the higher one. The battery was reached by a roughly 180-metre road built to Gamla Nynäsvägen, and the year 1908 is carved on a stone tablet above the entrance.
