A cathedral once stood in Aldera, which served as the capital city for the Core Worlds planet of Alderaan. This cathedral met its end, along with the rest of Alderaan, before 0 BBY, due to the Galactic Empire's Death Star battle station's destructive power. During her wedding ceremony inside a temple located in Bright Tree Village on the moon of Endor in 4 ABY, Princess Leia Organa reflected on the possibility that, under different circumstances, she might have married rebel General Han Solo in that very cathedral.
Beth Revis's 2022 novel, The Princess and the Scoundrel, included a reference to the cathedral.
