How to get to the bottom of Dungeon Destard in Ultima 5 Lazarus

In Dungeon Destard, I get from a cave environment to a stone wall hall with Ettins and Trolls, but cannot find a way to go down further. Is this the right way to go? I can see a corridor on the other side of the wall, but cannot blow the stone wall up. I don't see hidden lever either.

I searched Google and I don't see anything about "lazarus destard".

There is a button, that is well hidden, in a side room to your image.

Spoiler:

There are some walls that can be "attacked" to break them down. Inside these walls, are water troughs. The button is in a water trough.
