The Irish again:
During his travels Ramon de Perelhos visited an Irish place of pilgrimage, Purgatorium St. Patricii (st. Patricks Purgatory), where one could go down to the purgatory (1397). Source in German

More images of Dante Alighieri's travels through hell, purgatory (P. Vergilius Maro guiding), and paradise (with Beatrice) in La Divina Commedia In Italian.

Happy voyage
