This is not accurate information but cool
In the first comic of Star Wars infinities (where actually things change, Death Star blows up Yavin 4, rebels barely escape, Leia is captured and becomes an asset to the Sith, Luke presumes she's dead until he learns the full truth when he is a Jedi and decides to rescue her)
Anyway there Palpatine used the Jedi Temple as a sort of Sith temple.
The Jedi Temple is not made into a Sith Temple; the Jedi Temple is left in shambles as we see it at the end of ROTS and probably gets worse as time goes on. It's finally destroyed during the Vong invasions.
An the Senate Arena stays as the Senate Arena; the Senate isn't dissolved until ANH, remember? The Imperial Palace is actually constructed in the months and years after ROTS before ANH.

I told you that the information wasn't accurate...I think it wasn't really a temple...just a place where Darth Vader and Palpatine planned a lot...at least in the comic...But that isn't cannon.
That comic is far from cannon since the entire story is different. One change set off a chain of events altering everything.
They said the Imperial Palace towered above all other buildings on Coruscant, I'm assuming that it covered some area when it's this high, so there's a possibility that it may have been relocated away from the Senate. Too crowded there. Maybe.
But in ROTJ SE, the Jedi temple IS in the background, not clear as crystal, but that's it all right.
