The Monadnock Building
The tallest load-bearing masonry office building ever built.

The Monadnock Building at 53 W Jackson Boulevard is the tallest commercial building ever raised on load-bearing masonry — its brick walls are six feet thick at the base. Burnham & Root designed the northern half (1891); Holabird & Roche added the steel-framed southern half two years later, making the single structure a textbook of the moment Chicago invented the skyscraper.
It sits on Cook County parcel 17-16-233-001-0000 in the south Loop. Open the parcel record for its zoning and assessment.
