SPONTANEOUS AND REGULAR MODELS OF FORTIFIED CITIES OF UKRAINE IN THE 16TH–17TH CENTURIES
The Ukrainian frontier lands have introduced the principles of early-modern European urbanism which primarily included a defense component in the 16th–17th centuries. The inventory papers and studies of that time indicate that the presence of defense structures around the settlements was determined by the city status, which gave privileges and responsibilities to defend and keep both the city and castle fortifications.
