BHP Hall

This unassuming building inside Gdańsk's old shipyard is where Solidarity — the trade union that helped bring down communism in Poland — was officially founded in 1980. The hall hosted the signing of the August Agreements between striking workers and the communist government, making it one of the most politically significant rooms in modern European history. The weight of that moment still hangs in the air as you walk through exhibits covering the strikes, the movement, and the long road to Polish independence, with information available in multiple languages.
