"better known as"

Well, if Chehel Sotoun Pavilion is the real name, but people usually refer to it as Kolah Farangi Pavilion, then you could write it like this: ''That place is called Chehel Sotoun Pavilion but it's known as Kolah Farangi Pavilion.'' I believe it sounds better this way!

The real name is Chehel Sotoun Pavilion. I wanna know if it is possible to use the word "famous" somehow or not?

can you tell me which one is the real one
