One of the oldest structures still standing in the Town of Grand Falls-Windsor, Harmsworth Hall has served the community for almost 60 years.
The Town of Grand Falls was officially incorporated in 1963, and the company gave the building to the new municipality as a town hall. Since then, the city council has renovated the interior to include offices and council chambers. The hall still operates as the offices for the Town of Grand Falls-Windsor.
The hall has a wood frame with a brick exterior and stands two storeys tall. It has roof trim moulding, copper flashing and large arched windows that overlook High Street, the main street in Grand Falls. It has concrete lintels over the doors and windows, and the centre portion of the hall features a peaked roof.
Harmsworth Hall became a Registered Heritage Structure in 1998. It is one of very few heritage structures in central Newfoundland.
