<<This has been the subject of some debate among historians; although
providing 
the water would not have been a problem, it is unclear how the arena could 
have been waterproofed, nor would there have been enough space in the arena 
for the warships to move around. It has been suggested that the reports
either 
have the location wrong, or that the Colosseum originally featured a wide
floodable 
channel down its central axis (which would later have been replaced by 
the hypogeum).>>

Nem csak Teged erdekelt a dolog.
