Kamer-Kollezhsky rampart was a rampart which was built by Kamer Collegium and became the last of the Moscow city walls. After demolishing of the ramparts and gates it became a ring of streets around the center of Moscow, Russia. It is the third historical ring of Moscow, with a total length of 37 kilometers, partially integrated into the modern Third Ring circular highway. Kamer-Kollezhsky Val is not a road ring in the strict sense, as it has no crossings over the Moskva River.
