Giant Wild Goose Pagoda in Xian

The pagoda was built in 652 in the Tang Dynasty.

Additional stories were added on later but the pagoda suffered from a massive earthquake in 1556, reducing the number of stories to the present  seven.

It must be one of the tallest structures in the world when it was first built.

An engineering feat and achievement at its time.

Like the Pisa tower, it is leaning slightly to one side, although not as noticeable.
