Memorial Hall

Memorial Hall (メモリアルホール) is a location in Mega Man X4, a military building built solely by the elite anti-Maverick military organization known as the Repliforce to not only to serve as their main headquarters but also as the symbol of commemoration to their own members, most commonly those who have fallen in the ongoing Maverick Wars.

Description
The Memorial Hall is a giant mansion-like military building with a galloping pegasus status at its main courtyard and the entire building contains a number of rooms, including the main conference chamber and the Memorial Hall center-stage auditorium chamber. One of the windows on the main building is stained-glass and decorated with a painting of the Virgin Mary, the mother of the Lord Jesus Christ, which shows that the organization respected the figures of Christianity.

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, launch a Reploid-only nation, and become anfully independent organization.

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.
