Appearances Of Dolmens In Gochang Area, Korea

In this posting I’d like to introduce you each appearance of Dolmens in detail.
The Dolmens in this area had so various features.

In the entrance of the museum, there was a huge dolmen as same as a house.

The typical Dolmens were set up on the corner stones as below.

But there were so many dolmens without corner stones.

In my opinion, there must be some differences between the dolmens with and without the corner stones.
I guess there must be unknown meaning between two types of the dolmens.

It must've been very difficult jobs to make the stone monuments in those ages.
The ancient people should've made these dolmens to preserve for a long time and to say something to us.
What was that meaning they tried to deliver to us with these stone monuments ?

Dolmens in this area looked like the avant-guard art works.
Unlike other area, there is no advance in the art, we just find out the new aspects from existing ones.

Avant-guard art seemed not an advanced but a revival of the oldest art style.
