Cyclists who “own” a particular climb or stretch of road

I think Sagan owns the whole Adriatic coast from Chieti all the way up to Porto Sant'Elpidio. Now he has won five times in that area and three (perhaps four, I think Chieti 2012 was a bit more predictable) of those wins are among his most impressive wins ever on terrain that should be too tough for him (PSE 2013, Fermo 2017, Tortoreto 2020).

In the middle of that stretch of road, however, is San Benedetto del Tronto situated, and that may be some sort of Sagan-independent exclave which stands firm against his tyranny.
 
While confined during our state stay-home order I rewatched the 2014 Ronde, and loved seeing Cancellera put the hammer down on the final trip up the Ould Kwaremont. It got me to thinking how some pros have particular climbs or stretches of a race course that suited their characteristics so well that they virtually “owned” them. I’m not as knowledgeable as some of you but these examples come immediately to mind:
Canc: Kwaremont
Gilbert: Cauberg
Porte: Willunga
Valverde: The Mur?

What are other current or past examples?

Is it possible to have two owners or does Cancellara have to relinquish ownership of Kwaremont to Pogi?
