i dont know what it names in diamond but the name of it is Tin tower in jotho region. if you really want to know the answer,try opening the website www.bulbapedia.bulbagarden.net
After catching all the legendary dogs Suicune, Entei and Raikou Ho-oh will appear in tin tower situated in ecrutek town. Also I think you might need the Rainbow Feather
You can find Ho-oh by taking the left path in Island #8. Pack some balls and potions Save first before fighting with Ho-oh then you can fight with it but be careful not to kill it or just use the masterball, that ball catches any pokemon without fail. Jean:)
