Top of the Hub’s Skywalk Observatory (459 feet)
From the observatory perched 50 floors above Back Bay, visitors can see west to Mount Wachusett, east to Marblehead, north to Mount Washington, and south to Cape Cod on a clear day. Try to trace the Marathon route from Hopkinton, locate Boston landmarks, or just watch the traffic below. An audio tour helps make sense of the landscape, while exhibits provide historical and architectural information. Food with a view is available two floors above the observatory at the Top of the Hub restaurant. New England clam chowder and Boston cream pie are on the menu, of course.
