From the south towards the sea two brothers were wandering: Byd and Gost. They were passing by meadows, lakes, forests, hills, valleys and swamps ...
The journey seemed to have no end. Byd was looking for dense woods that could provide construction materials for a settlement. Gost on the other hand kept his eyes open for a river rich in fish and large enough to protect a castle from the invasion of enemies.
After many days when the River Brda appeared in front of their eyes, the brothers decided to end their journey. The forests here were extremely robust, and lakes were scattered among numerous meadows. Additionally, the land was crossed by a junction of routes linking the north with the south and east with the west. The place was convenient, so they established a settlement here and called it after their names - Bydgost.
