观星台

Using this observatory the Chinese managed to calculate the length of the day to within 12 seconds of the value we know today.Unfortunately on the day we went, air pollution prevented us from getting a shadow.There are marks from 2nd World war Japanese shells fired at what they took to be a military observation post.We were the only people present on the day we went apart from our guide and the staff. Our guide said he only went here about once a year as it wasn't that popular.There is a second scale model which makes it slightly easier to understand what is going on.Remember that noon is when the sun is overhead and with all of China on a single timezone, the local noon might be somewhat different to what it says on your watch.It could stand improvement of the explanation with diagrams and more English text.Probably not suitable for small Children with a short attention span. Incidentally we found a scale model of this in the Beijing science museum.

世界遺産、「天地の中央」にある登封の史跡群（８つ）のうちの一つです。その中でもこれは観星台と呼ばれ、昔の天文観測施設になります。インドにあるジャンタルマンタルが思い出されました。特になにがあるわけではありませんし、少し交通の便も悪く行くのに時間もかかります。天文などにに興味がある方は楽しいでしょう。

Gaocheng Astronomical Observatory is very close to Dengfeng , a short visit to the site and watching some important Astronomical instruments at the site absolutely did not waste your time. There are not many visitors at site and a short and close visit is possible and fun.

I love astronomy and thought this would be a place of interest but in the end I felt it was a waste of time. I would have enjoyed hanging around my hotel, ChanWu longer and just watch the kids practising kung-fu. I've been told by my guide, Charlie from China Odyssey Tours, not too many people visit this place. It's interesting to see the apparatus they used in determining when the seasons would be arriving, also, to see the damage from a cannon ball during WWII from Japan along the side of a building. Overall, I would have loved to spend my time more at the Shaolin temple.

Merita una attenta visita se non altro per avere la dimostrazione che gli antichi non erano degli sprovveduti come si può pensare. Notevoli poi i "Sistemi di Studio" dell'Astronomia. E' consigliabile una guida che spieghi bene il tutto.
