Heartland Memorial Hall, known as Heartland Memorial in the Japanese version, is a building in Heartland City dedicated to Mr. Heartland after his "death". It was filled with busts and statues of Heartland himself. When Heartland returned from the Barian World, he and the rest of the Fearsome Four of the Dark Dueling World used the memorial as their headquarters. It is shown to be abandoned, with several of the display cases being smashed open. When Yuma Tsukumo's friends arrived, they used them as bait to lure Yuma there. The building then became the site of a Duel pitting Yuma and Trey against Erazor.
