We greatly value what you think about kastellia.gr! We feel that by receiving your valuable opinion we can then truly serve your needs to the fullest by constantly improving our services.
For that, we ask that you send us your proposals, as well as any material you would like to see published on kastellia.gr (e.g. pictures, sounds, etc. We would recommend though that before you send us large size files, you use a compress utility - like winzip - to first zip the files and at the same time pay attention that each time their size does not exceed 3MB).
You can send you proposals and any material you want to place on our Portal at
