The Ballard Centennial Bell Tower
was created to hold the old Ballard City Hall bell at the site where the City Hall stood, and to mark the Ballard Avenue Historic District. There’s an inlaid compass in the floor of the bell tower. The tower is located in Marvin's Garden, a quiet oasis across the street from Bergen Place Park in Ballard.
