Also, the 3.5 era book City of Splendors details that there was a public teleportation circle in Waterdeep, between the inner and outer walls of the South Gate. It was very distinctive, making memorization easy, and well-watched by the city guard to prevent abuse or misuse.
There's no reason the circle couldn't have survived the Sundering, though I'm not aware of any 5e source that mentions it.
