Locked gate and door in sewers

[ozymandias]

There is a locked gate and a door in the sewers near the final eye. I saw it last time I was in the sewers but ignored it. This time I tried to find a way of opening it but can only find the the two switches that open the way to the final eye. Can it be opened? Is it worth it?

There's a couple of doors behind locked gates in the sewers, I don't believe either can be opened, just a teaser from Indi.
