The Eagles hotel is mentioned in 1844 and shown with its present plan on the 1852 town map. Brewery sign brackets are dated 1856.

The interior has been modernised and the plan has been altered.

It has been listed as a mid C19 public house built in the context of an expanding middle-class suburb, retaining early character and notable for its decorative cast iron signs.

The Eagles hotel is a 3-storey public house with a V-shaped plan on a corner site. The front is rusticated stucco in the lower storey beneath a moulded cornice, and has late C19 roughcast in the upper storeys with smooth-rendered eared architraves to the windows. A hipped roof retains original graded slates on moulded eaves, with rendered end stacks. The Newborough Street elevation is 3-window with 12-pane sash windows in the middle storey and 9-pane in the upper storey beneath the eaves. An iron sign bracket to the L in the middle storey has scrollwork decoration around the date and arched lamp holders. In the lower storey, where the openings are altered, is an original doorway to the L converted to a window, then 2 large inserted windows, a doorway with overlight to the R of centre, and original window on the R replaced by a late C19 2-pane sash. The wall continues to the R and encloses a yard behind.
