My name is Maxim, and I am currently residing in Warsaw, Poland. Recently, while walking along the Vistula River, where the water level has dropped, I noticed several old bricks exposed near the roots of a tree. Among them, I found a fragment of ceramic, possibly from a square-shaped object, with what appears to be a version of the British Royal Arms on one side, featuring a unicorn and a lion.

This discovery has sparked my curiosity, I am amazed at the idea of holding a piece of history that may have traveled so far from its origin. I would be incredibly grateful for any information you could provide on the potential origin, manufacturer, or age of this ceramic piece, or any other resources or experts who might be able to assist me.

Please find below secure links to photos of the ceramic fragment I discovered. Unfortunately, your contact form does not allow photo uploads, so I’ve used a trusted image hosting platform to provide access.
Thank you for your time in reviewing these images.
