This is an inspection shaft in the 5th century aqueduct channel in Thrace. It comprises an opening in the vault of the channel covered by stone slabs that could be removed from the ground surface. The inspection shaft would allow people to access the channel to carry out maintenance such as clearing debris, removing or smoothing sinter build up and replastering.
