Not sure if the Opera de Versailles is free to visit on Sundays or free everyday, and even if it isn't, the Opera House is definitely worth a visit. Unlike the Paris Opera, you can visit the entire ring(colossus?) and walk in front of the stage. Or you can just sit in the Opera, with the staff's commentary, you can feel the chambers of the king of French and nobles. You can take your kids to listen to the popular science of the staff. But remember to keep quiet when passing by the actor's rehearsal room🤫
