I am trying to use alchemy-cms within an existing app. I have an application layout including a menu bar which is linking to several controllers in my page.
I have mounted alchemy-cms as engine, which works fine.
When rendering a page created with Alchemy in my application layout, I get a routing error, because my other controllers are not available within the Alchemy engine and its page_controller which is rendering the site (at least that seems to be problem).
What I want to do is have some pages created/rendered by the Alchemy engine and some pages are created by other controllers. Isn't that possible?
Or, more generally: Is it possible to access the routes from the main application inside a mounted engine?

It is.
You should mount Alchemy at the latest point of your routes file. (After your custom routes, because Alchemy comes with a catch all route)
That means if one of your custom routes matches - it will be used. The Alchemy routes will be used if nothing else has matched before.
# routes.rb
MyApp::Application.routes.draw do
... all your custom routes ...
mount Alchemy::Engine => '/'
end

I think your question is not how to access the main apps routes from within the Alchemy engine because you are working in your main app, not in Alchemy - Alchemy just comes in as a gem.
You can always access your main apps route object like this:
main_app.routes
Or the url helpers:
main_app.new_photo_path
You can access the engines routes (in this case Alchemy) with this helper:
alchemy.routes
