Well i do believe that these tiles are the essence of Korean Culture but this is also so true that conqueror always destroyed the monuments of the occupied region, Alas!
Actually the roof tiles of Goguryeo were the most powerful warrior style. And that of Shilla was a mescaline style. Back Je had a feminine and an elegant style.
Yes,i felt a little bit difference among the tiles of both region, In #Shilla tiles i found that they used to love animals that is why they sketched them in the tiles while #Baek_Je tiles did not show any animals sketches in the tiles, am i true my friend @slowwalker ?
Your have razor eyes.
I didn't notice that.
