This is the full view of the Alter of Heaven, a place where the emperors of China used to make sacrifice to heaven. I got this from the back of the alter, so not many tourists blocking sight. Of course, seeing is not enough. You have to be there to experience its scale, especially the square on which the whole temple was built.
One pity is the sky looked grayish. But it is really becoming harder to have a blue sky in Beijing nowadays, not to mention clear air.
This is a closer look of the alter. The exquisite style is quite characteristic of the buildings in Qing Dynasty. To get a look at the inside is almost impossible, not only because access is not allowed, but also because of too many tourists blocking you away from the door narrowly open on the other side. I wish next time I could come at 6 a.m. when others are still in bed!
