As in her previous album Ceremony (2012), The Miraculous contains a pipe organ, which was recorded at the Studio Acusticum concert hall in the Swedish city of Piteå.

When writing the album, Von Hausswolff took inspiration from a place where her family used to tell her stories as a child, and the book Källan by Swedish writer Walter Ljungquist.

The Miraculous takes its title from the name von Hausswolff gave to a then-undisclosed village in Sweden that she visited with her family since her childhood.

[2][3] Historically, a 1542 uprising against the rule of Gustav I happened in that location, in which peasants from Småland protested the heavy taxes imposed by the king but ended defeated.

[6][7] The album was also inspired by her instrumental recording Källan performed at the Lincoln Cathedral, which was named after the 1961 book by Walter Ljungquist.

[9] Von Hausswolff recorded The Miraculous with her backing band and producer Filip Leyman at the Studio Acusticum concert hall located in Piteå, Sweden.

[2] A friend of Von Hausswolff presented the song "Come Wander With Me", written by Jeff Alexander and Anthony Wilson, to her and became one of her favorite compositions.

[17][16] The singer is accompanied by her backing band, which consists of Leyman on synthesizers, drummer Ulrik Ording, and guitarists Joel Fabiansson and Karl Vento.

[18] John Freeman of The Quietus described it as "a huge, brooding record that fuses ethereal fantasy with the portentous drama of rumbling organ drone.

[23] Von Hausswolff and guitarist Vento recorded a live session for "Stranger", which was uploaded to the singer's YouTube channel on 2 December 2015.
