Minecraft building idea for mountain?

Moin, I'm unfortunately without ideas what could come as a connection. Either a bridge up or into the mountain. This is a castle made of quarry stone with a nether tile roof. The main tower is said to be left on top of the mountain. Who has ideas to combine that? Gladly as text or examples as a picture

You could build a bridge in the rock face opposite and then go up a flight of stairs. You can vary degrees or spiral stairs.
