Explanation:

In the context of this poem, the walls do no seem to be a structure designed to keep a foe out, but rather to trap something within. The telltale sign that the walls are perhaps not a beneficial thing is the word narrow.

Walls can be protective, but in a narrow context it is implied that the barrier causes suffocation and perhaps claustrofobia.
