Saturday's parting shot

A view of Grace Church on 10th Street, where Broadway bends to the south-southeast. 

What's the scaffolding about? Per the church's Instagram account two weeks ago:

Restorations have begun in the south nave of the church, which is badly damaged from years of water infiltration. Over the next few months, you will see scaffolding inside and outside of the church as we work to restore the sanctuary and address the source of the leaks. We have tented the scaffolding and plan to vent the dust to the outside, so services will continue as usual.
