"It's a studio down in the depths of this huge high-rise building... with no windows and no contact with the outside world," May explained.
"[Led] Zeppelin did a lot of recording down there, as did Deep Purple... but it was an utterly depressing place."
The 65-year-old told Contactmusic that the eerie mood and sense of isolation meant he used to hate the place.
"People used to commit suicide by jumping off the top of that building quite frequently," he added.
May also revealed that locals introduced him to the legend of a malevolent wind that blows through the city causing havoc.
"They have this thing in Munich called 'The Fohn' and when The Fohn blows... people go nuts and they commit suicide," he said. "It was a real strange place."
May, who has set up an animal sanctuary in the grounds of his estate, played mini-festival 'Wildlife Rocks' in Guildford yesterday (September 1). The event was described as a "celebration of wildlife... through music and talk and fun".
