Preventing climbers into fortress

Preventing climbers into fortress - The Neuschwanstein  Castle on the Hilltop in Schwangau Germany

My last fortress was destroyed ,dwarfs were killed and then I abandoned it. goblins came in the fortress by climbing walls ! (yes I didn't expect them to climb walls).

I thought of an idea to prevent them from climbing ,but I am not sure whether they will come inside by climbing it or stay outside ? I think this screenshot from minecraft can roughly explain the design.

(red line is the enemy path)

I wanted an open roof fortress not a fully covered top of fortress by floor. so is this feasible ?

Climbing smoothed natural stone is impossible.
So smooth your walls from the inside. Note that carved fortifications are carved through a smoothed wall, and constructed fortifications are considered smoothed also. If you REALLY want to prevent climbers and flyers, build a floor over your fort. Gaseous creatures might still enter through your fortifications though.
Beware of jumping creatures. They will jump over your moat, even if it's filled with magma, then grab onto a rough wall.
Ghosts will just fly through anything, including solid rock.

Edit: I'm pretty sure an overhang, like in your picture, prevents climbing too. However, enemies could just climb around your walls and moat, on the rock face against which you built.
