It sounds like you might be referring to a situation or story where there are mysterious or intriguing events or secrets associated with gates, perhaps in a fictional context or a real-life location known for its enigmas. Gates often symbolize entry points into new realms or experiences, and they can carry a sense of wonder, danger, or the unknown.
If you're looking for a deeper exploration of this theme, there are plenty of examples in literature, film, and folklore where gates or doorways lead to mysterious places—think of the wardrobe in "The Chronicles of Narnia" or the gateway in "The Lion, The Witch and The Wardrobe."
