Stuck in room 15933

[SandyBean]

Thanks Freddy !  I found the long gallery, and had lots of fun exploring it, but now have found two mazes (rms 16538 - 16542) and (rms 16139 - 16137) that I cannot for the life of me figure out how to get into.  They look like they have entrances from below, and I have gone back into previous rooms to search, including room 16135, but cannot find a way in, or the rooms directly below the mazes.  Please help, I am desperate to continue!! :o

thanks,
Sandybean
