You can see Adler Planetarium from the Sky Park at MDA City Apartments, 63 E Lake Street. 

The Chicago Architecture Foundation arranged with building owners and tenants to give the public access to awesome spaces this past weekend, on Saturday and Sunday. Aside from frustration with the interface and design problems with the website, I thoroughly enjoyed each site I visited. View a list of all the sites that were open.

I checked out:

Inside the Christian Scientist chapel at 55 E Wacker Drive. 

The Kingdom Tower in Jeddah, Saudi Arabia, was designed by Adrian Smith + Gordon Gill Architects. And it’s actually going to be built.
