Explorers in Zlocieniec dug for the copper cylinder at the remains of the Ordensburg center after learning it could hold a documentary movie showing celebrations of the town's 600 years, in 1933.
At the time, the city was in Germany and was called Falkenburg.
Sebastian Kuropatnicki, spokesman for Zlocieniec authorities, said Tuesday they were curious to see the movie.
When the container was opened September 13, it held no film but did have the center's 1934 founding act on parchment, a letter, coins, photos and two copies of Hitler's book.
