I missed your earlier blogs about this museum. Was surprised that a collection of pipes from the Middle Ages existed, let alone in a Cossack fort. Sent me looking for more information....found a page dedicated to this museum and Ukrainian tourism. You probably are familiar with it. Plumbing in the Middle Ages? Aquifiers? Fascinating.
Many thanks for your informative reply! I did not know about the existence of "Ukraine travel blog | About Ukraine in English" and glad that this post motivated you to find and to share more information. I appreciate it very much :D
