In 2017, the Amber Mine was established at Fort Anioła. As the organizer informs:

"The rules of the game are simple: Grab a special sieve and start mining real Baltic Gold! Find the largest pieces of amber and take them home with you! Compete with family and friends! The fun lasts for 15 minutes. Organized groups of 15 or more are requested to contact us in advance for reservations. The “Mine” is open for individual guests from May to September."
