Thanks for submitting the Sanxingdui review, Zoe. I should have written one a long time ago myself, definitely a thumbs up.

Regarding the 3rd location: this website names an address (No.58 Shangye Street, Qingyang District, Chengdu City), which seems to be at a different spot. Tripadvisor has it at yet another location. At none of the three locations within Chengdu I find a hint in Google maps that a museum is located there. How sure are you about the coordinates you shared?

Looking forward to your addition for the Shu state reviews!

As for the coordinates, they are from the WHS documents. I went around the block of Shangyejie on Baidu map and there is no sign of a museum. So I suppose leave that blank until someone knows it for sure.

I was there in 2007! But I do have my pics and diary in Dutch so can fabricate something.

Here are the coordinates of the 12 locations of the Porticoes of Bologna TWHS.
The source is the Executive Summary, the T-list entry does not provide any information on the selected components.
