Named appropriately for a mountain in New Hampshire, the Monadnock was the last tall building to be supported by its own walls (not a metal frame, although the 1893 addition by Holabird & Roche does use one). It's a masterpiece of simplicity and power in form. The block-long hallway that serves as a
lobby has incredible ambiance: it's always kept at a level of brightness that suggests gas lamps, and the small stores on the first floor (a coffee shop, a shoe-shine, a restaurant) are all turn-of-the-century tile-and-polish.
