At the museum in Sukhothai we got to experience the Mystic Tunnel Like Stairway Corridor.
Actually a recreation of the Mystic Tunnel Like Stairway Corridor, which was actually in a wat somewhere.
With pictures of the stone carvings and the view out of the temple mounted on the white painted walls.
It was considerably less exciting than it sounded.
They also had some ancient carvings from the temples in the area, including this nail biting daemon.
And an ancient toilet-hole covering.
And some 15th century water pipes.
