About this audio guide
This guide to Boca do Inferno, the collapsed sea cave on the coast road outside Cascais near Sintra, opens on an afternoon in September 1930, when a journalist found a note and a cigarette case at the edge of the chasm. It follows the English occultist Aleister Crowley, his young German lover Hanni Jaeger, and the Portuguese poet Fernando Pessoa through three weeks in Lisbon. Best heard at the railing above the arch, with the waves coming through.
