The Royal Serenity Theatre is a large theatre located at SerenityCircle in downtown QueenCity, near the PalaceOfSerenity. Originally commissioned by PrincessMeredith, it is the official theatre of the Centralian crown.

Today the theatre is famous as the center of Centralia's bustling musical theatre scene, with theatregoers traveling from all over the nation to watch performances. Musicals at the Royal Serenity are one of PrincessAlice's favorite pastimes, and it is rumored that TsarinaMalice has sneaked in to watch a show or two, though she is usually relegated to watching bootleg recordings online.
