In addition to an international certificate for working castles worldwide, numerous countries also have national programs with the same objective.

As with the flora & fauna areas, the list of references is becoming endless. Unless I happen to meet them on the band by coincidence , I do not actively hunt for these references.

You may find some useful information here.

Chasers of the Belgian Castles & Fortresses award, please note that a signle QSO with ON4CAS and/or ON3EBR is valid for four different references:

1. ON-01082 – Hof van Busleyden
2. ON-01083 – Paleis van Margaretha van Oostenrijk
3. ON-02407 – Kasteel Caputsteen
4. ON-02411 – Kasteel De Borght
