Path of Remembrance and Comradeship

The Trail of Remembrance and Comradeship, also referred to as the Trail Along the Wire, the Trail Around Ljubljana, or the Green Ring, is a gravel-paved recreational and memorial walkway almost 33 km long and 4 m wide around the city of Ljubljana, the capital of Slovenia. The walkway leads past Koseze Pond and across Golovec Hill.

During World War II the Province of Ljubljana, annexed by Fascist Italy, was subjected to brutal repression after the emergence of resistance. The Italian forces erected a barbed wire fence—the route of which is now the Trail of Remembrance and Comradeship—around Ljubljana to prevent communication between the city's underground Liberation Front activists in Ljubljana and the Slovene Partisans in the surrounding countryside.
