Constructed between 632 and 646 AD Chomsongdae is one of the
world's oldest observatories. It's also one of the most fascinating - there
are 30 layers from top to bottom, one for each day of the month. The 12 base
stones are for the 12 months of the year and the whole bottle-shaped observatory
was constructed of 366 stones, one for each day of the year (or so they thought
. . .). Other details of the structure reveal the designer's knowledge of
astronomy, geometry and the stars.
