CHICAGO, IL – Below are before and after pictures of the tower northeast corner at the very top. The corner stone had shifted at least 2 inches. The stone was removed and reset. SGH (Simpon Gumpertz and Heger) will be able to access the area on Monday to do a full assessment of why the stone moved and also, provide details on how to adhere the stone back in place. The roof above is four large pieces of limestone, all in good condition, and may need some tuckpointing.
