The corbelled tholos at Mycenae sets a record that stands for fourteen centuries

node

The Treasury of Atreus is built into a hillside near Mycenae with a corbelled chamber roughly 14.5 m across. No larger roofed interior space is built anywhere until the Roman imperial period, and the technique that holds the record is corbelling - a cantilever, not an arch. The relieving triangle above its enormous door lintel shows the same builders solving the bending problem the only way available to them: by removing the load rather than by resisting it.

A node is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
