This is a place by the Vepriai camp building where the campers light a bonfire. At least that's my guess.
Vepriai is a village in Lithuania where E went to the 10-day summer camp ("Vepriu stovykla") in July of 2019. Despite the language barrier (E did not learn much Lithuanian in time for the camp) she enjoyed it. Most of the kids in the camp, majority of which were Lithuanian, spoke good English, so language did not present a barrier.
