• Dègueulasse means "disgusting" and marais "swamp", but the former is an adjective that follows its noun, so "the disgusting swamp" is Le Marais Dègueulasse. The writer may have meant to use "disgusting" as a noun and "swamp" as a qualifier, which would make this "the swamp disgusting thing". This seems unlikely, though.
