Jordan's "Rose City" (5)
I believe the answer is:
petra
(Other definitions for petra that I've seen before include "A rose-red city - 'half as old as Time'! (Burgon)" , "Burgon's rose-red city" , "Rock-hewn city of Jordan" , "Ancient Asian city, now in Jordan" , "Long-lost city of Jordan rediscovered in 1812" .)
