Documented another type of monument, unknown until recent aerial surveys. Some call it a Motte while others claim it's a knightly or even "provost" village. Anyway there's tons of them. The last example is from previous years. Shows how they look in nice conditions for #cropmarks

Tying in to the previous posts about #medieval abandoned towns, see the reconstructed schematic town plans of royal Nieszawa and private Dzwonowo. Note the difference in size between a private and royal charter. Bonus aerial image with #cropmarks of Dzwonowo.

Crop marks are thin lines at the corners of a design that show printers where to trim ✅Ensure precise cuts ✅Prevent unwanted white edges ✅Essential for full-bleed designs Always include them in professional printing #CropMarks #PrintingTips #DesignEssentials #jrshooterprint


Incredible to read that - following its aerial discovery & evaluation during a solar farm development - the importance of the buried site was recognised & it was both scheduled & taken out of the plough. Wow. More of this please! 👏👏 #AerialArchaeology #Cropmarks

Not really sure - it might be soil chemistry due to chalk being used for the tracks. They are very striking! #cropmarks
