The Port's Sewers

[Orchid Queen]

I am having a major senior moment. I want to access the sewer and the walkthrough tells me to go down to the ports. For the life of me I can't find where to go. I must have been there before now but my memory of it has gone. As I say, a major senior moment.
Can anyone refresh my memory, please, and tell me where the Ports is?
I'm getting old!

If I remember correctly, Port is east from The Fighter's guild. After entering Adretana, at the Gates of Adretana, go right and then right all the way (to be more precise it's right, then down at the end, right again I believe).
