I think I understand the meaning of this sentence, but I don't understand how it's constructed.
I'm assuming ansteigen (to rise) is the verb, and ein Kuppeldach (a dome) is the subject and Nach der Mitte means 'towards the middle', but I don't understand the role of the words zu, sie or wie.
I'd really appreciate any help.
Nach der Mitte zu
|stieg sie an
|wie ein Kuppeldach
, and that may help you to understand the structure – äüö Sep 6 '13 at 11:53
