Garreg Mach Monastery

The Garreg Mach Monastery is a downloadable stage in Super Smash Bros. Ultimate that was released on January 28, 2020 alongside Byleth. It takes place at the Garreg Mach Monastery, a location that debuted in Fire Emblem: Three Houses as the headquarters for the Church of Seiros and the Officers Academy, and where Byleth teaches their students.

Similar to stages such as Delfino Plaza and Prism Tower, the stage travels through different locations in the monastery on a flat moving platform, though the transition effect resembles the one seen on Castle Siege. The locations that the platform stops at include the Marketplace, the Reception Hall, the Bridge, and the Cathedral. Similarly to Mementos and King of Fighters Stadium, several other characters from Fire Emblem: Three Houses make cameos in these areas: Dimitri, Dedue, and Ingrid from the Blue Lions House appear in the Marketplace (as well as the Gatekeeper standing in the background), Edelgard, Dorothea, and Petra from the Black Eagles House appear in the Reception Hall, Claude, Hilda, and Lorenz from the Golden Deer House appear on the Bridge (as well as a Pegasus Knight flying in the background), and Seteth, Flayn, and Rhea from the Church of Seiros appear in the Cathedral.

In the Marketplace, fighters can destroy the two vendors on each side allowing for the length of the stage to expand. In the Reception Hall, fighters can attack the chandeliers to make them fall, though some fighters are unable to reach them. The tables in this area can be destroyed as well. In the Cathedral, two pass-through platforms appear on each side for fighters to jump on.
