Please describe a spooky scene inside of a medieval prison with bars and a porthole of glass.

Hollow metal columns rise from the platformed floor to the domed ceiling, forming a makeshift skeletal structure that holds up the roof of sliding steel sheets. Walls rise up on either side of the hallway, stopping short of the concave dome high above. Three sturdy bars cover a heavily reinforced porthole of glass in one wall, and little can be seen past it except the occasional splash of water hitting its interior.
