The Hancock Center was once Chicago’s tallest building and the world’s second tallest. Not for long—within five years it was locally eclipsed by the Aon Center (which entered life as the Standard Oil Building) and then the Sears Tower. Still, at 1,127’ and a round 100 stories, ‘Big John’ still makes a grand end to the Magnificent Mile.
And if you want to look out over the city, what’s a few hundred feet? Its Observatory may be 323' below its competition, the Sears Tower SkyDeck, but it sits closer to the lakefront, amid the city’s commercial district (while Sears is on the far west side of the Loop). And the Hancock is open until 11pm, allowing for a late, late night look (the Sears closes at 8pm Oct-April).
We gazed upward at the Hancock during our walk up Michigan Avenue, admiring its black exterior, a great example of graceful form following function. The building’s X-braces, the iconic series of exterior diagonal crosses, are part of the ingenious design of skyscraper architectural engineer
par excellence Dr. Fazlur Khan (also responsible for the Sears Tower). These transfer a large part of the building’s load to the exterior, freeing up more interior space.

None of that was on our minds as we wound our way north, sprinting between awnings to avoid as much water and wind as we could. After a detour on the warm, indoor escalators of Water Tower Place, we crossed the street into the Hancock’s sunken plaza and the west entrance that leads to the Observatory’s ticketing area.

After paying ($10.50 adults, $7.25 kids), we had a brief wait amidst wall-sized blueprints. The 20mph elevators then took us from basement to 94th floor (or 95th floor restaurant) in 40 seconds.
Last view of the cityYou exit facing the lake, and can walk completely around the 94th floor, which is all windows, floor to ceiling. The one exception is the skywalk along the south side, where you step outdoors on to a very securely screened-in patio, good for an extra dose of adrenalin if you, like me, suffer from agoraphobia.

Below and to the left were Navy Pier’s lights and ferris wheel; to the right stretched the Lake Michigan shoreline. The ladies who staffed the observatory were already bemoaning the limited visibility from the night’s clouds ("If you’d been here at 7, you could see 80 miles"). The increasing fogginess added additional difficulty to picking out landmarks, but we had fun circling the floor and enjoying the clouds and moisture that gradually reduced our view to zero.
In addition to the view, the Observatory features a small but decent history of Chicago on three or four large panels, a series of interactive video displays, and (of course) dollar bill-operated telescopes. Along the north side, a little booth lets you photographically record your career as a simulated window-washer, and a small gift shop will take your money if you just have to have a souvenir.
