Zaryadye Park, designed by High Line architects Diller Scofidio + Renfro and located on the site of the old Soviet-era Rossiya Hotel, isn’t having trouble because of shoddy work. (Not with those architects, nor with the personal interest of Vladimir Putin.) The problem is vandalism: the first day, someone threw an object through the glass roof of the media center and concert hall, and more than 10,000 plants in the park have been trampled or stolen.
