Memorial Hall

Memorial Hall is a location in Mega Man X4. It is a major place of assembly for Repliforce.

Description
Memorial Hall can be seen in the cutscene after the opening stage. Repliforce holds a large assembly in the hall, where General formally announces their coup d'etat to separate from the rest of the world.

After X or Zero defeats the first four Mavericks, Colonel challenges them to come duel him at Memorial Hall. X's encounter with Colonel is a boss battle taking place just outside Memorial Hall, with the large structure in the middle visible in the background, while Zero's encounter is a cutscene wherein the two fight right in front of the structure before being interrupted by Iris.
