"Seven Doors Hotel", written by Joey Tempest, was the first single released from the Swedish heavy metal band Europe's self-titled debut album. It was a big hit in Japan, reaching the Top 10. It was one of the first songs he ever wrote.
Tempest was inspired to write the song after seeing the Italian horror film The Beyond.
In 1985 Europe recorded a new version of the song, which was used as a B-side for the single "Rock the Night".
