It's really amazing. The Millennium Tower is prominently at the center of almost every major radial street from downtown in pretty much every direction.
It's cool that the tower accentuates how much it's at the center of ye olde Bostone (DBA Downtown Crossing) and how much of the surrounding area has been historically oriented in that direction.
Has anyone else noticed the odd, darker-colored window treatments on the most recently installed course of the sheer wall? You can see it in Boston02124's last picture. I can't tell whether these are placeholders for the actual windows, or something I should be concerned about (because at this juncture, it doesn't look good). They had been using plywood in other areas that weren't complete. Perhaps someone else has a better idea of what's going on?
I think you mean curtain wall, yes? The shear walls (massive concrete walls designed to prevent the building from falling over) are internal in this structure. I wouldn't be concerned about the glazed curtain wall's current state of completion. It should be consistent all the way up, as AFAIK, that location on the building is a regular condo floor and not an interstitial MEP level.
