That is the curb material in all of the older (pre-WWII) parts of
Washington DC. The only thing that seems to tear it up is road crews
widening the road. It is tough stuff.

Actually not.
All the "Belgian Blocks" being sold these days are coming out of India.
The most common size used for curbing is the "Jumbo", which is nominally
8 x 11 x 4" thick.

DC curbing, OTOH, comes primarily out of North Carolina, from the
N.C.Granite Corp, and is known as Mt. Airy Granite. DC curbing is about
8" in the street to sidewalk dimension, and 12" or more deep, and in
lengths that typically range in length 5 or 6 feet. Certain not
cobblestones by a far cry.
