Over the years, many additions have been made to the Hogwarts Castle. It's a honeycomb of hidden passages (both truly secret ones and those that are simply useful shortcuts to class), hidden rooms like the Room of Requirement and even the occasional trick stair or wall masquerading as a door.
It makes sense that a single student is unlikely to uncover all the mysteries the castle is hiding, even in 7 years. But I still think we all stand at least a slim chance of discovering some magical quirk of the castle that few if any people have found before us. If only we knew where to start looking....
So, what hidden room or other little-known feature of the castle that didn't make it into the books would you like to find during your time here?
Personally, I think the dungeons could do with a thorough exploration. There have to be interesting things down there that have been forgotten about over the years. It would be interesting to see how old spells might have evolved and changed their surroundings after years of being left unattended....
