Was this actual unicorn also found at the site?
A unicorn lair in North Korea? Sure. Why not?
From the Telegraph:
I just love the proof that it's a unicorn lair-- a rock that actually says "Unicorn Lair." Well, I'm convinced.The quite unbelievable claim of the discovery of the unicorn lair belonging to King Tongmyong, founder of the ancient Korean kingdom Koguryo was made by the History Institute of the DPRK Academy of Social Sciences.
The lair was apparently found 220 yards fro[sic] a temple in the capital, Pyongyang.
"A rectangular rock carved with words "Unicorn Lair" stands in front of the lair. The carved words are believed to date back to the period of Koryo Kingdom (918-1392)," the report said.
"The temple served as a relief palace for King Tongmyong, in which there is the lair of his unicorn."
The report was also used to make a more serious point about the North's claims of dominence over the South."The discovery of the unicorn lair, associated with legend about King Tongmyong, proves that Pyongyang was a capital city of Ancient Korea as well as Koguryo Kingdom," it said.
And just more proof that all of what has ever been historically good and noble in the Korean society happens exclusively in the North. Yup. Cast iron proof. No doubt.
