Here is a picture of the site of the moat that surrounded Tabríz, where the Báb's body was thrown: Bahá’í Media Bank
I don’t get it. Why was it covered? What the use of a moat if it is covered with walls and ceiling?

Looks like a bazar to me, possibly built on the site of the moat.

Anyone know if the term used for "moat" could also mean something like "gutter" or "drainage ditch"??

More than likely built upon later, since their bodies are thrown on the banks of the moat surrounding Tabriz.

It does now look like a market place.
