Built in 1912 to serve Palmnicken’s amber-mining plant, it showcases Brick Expressionism with red brickwork, carved stone accents, and arched windows. Inside lies an 800 m³ reinforced-concrete reservoir and a central spiral staircase leading to a 27 m‑high viewing gallery. After decades of disuse, it was restored in 2015–2016 and converted into a mini-museum of the amber trade, displaying tools and amber specimens.
