ugly lines on what should be a smooth surface

[Jinx786]

Hi!

I am modelling a tower, and I noticed that on smooth walls there are some ugly lines. Now I searched around a little bit and thought that n-gons might be responsible. So I went creating tris from n-gons, but some lines still persisted. Could you please instruct me on how to get rid of this menace? Thank you!
