Central European origin

[Aga Tentakulus]

If I would take the VM castle and connect it to the base Bellinzona, the upper part of the VM would look like the example.
The listed ruins belong to the same line of defense as the castles in Bellinzona. The age is almost identical.
If you read through the reports of the reconstruction, it also answers some questions about the battlements and dating.
The article about castles in general is also worth reading and helps for a better understanding.
I personally do not consider it to be the place of origin, but it is a good example.
