I recently wrote about the Wawel Castle in Krakow on the banks of the Vistula River, which I enjoyed watching during a river boat trip.
As our boat approached the shore, I took many shots of this amazing royal castle, where the history of Poland has been created for centuries.
I thought that all these magnificent towers and walls would look beautiful in black and white, and present their work to you.
Some shots used portrait mode, which gave an interesting blurred effect.
The photos were taken with my Xiaomi MI A1 smartphone. November 2018.
