No, this is not a photo of a shrine to the Prophet Mohammad in a mountain cave
A photograph posted on Facebook and shared thousands of times purports to show a shrine to the Prophet Mohammad in a mountain cave. Other versions of the image which have been shared tens of thousands of times show statues of the Hindu god Shiva or the Buddha in the same location. The photographs are all doctored versions of an original image of a cave in China’s Tianmen mountains, where there is no statue or shrine.
This January 27, 2019 Facebook post, which has been shared nearly 6,000 times, contains an image showing a set of stairs leading through a mountain forest to a cave where the Green Dome from the Mosque of the Prophet appears to sit in a beam of light.
The caption says: "Muslims should share, infidels should ignore. Glory to Allah, Like, Share."
This September 13, 2017 Facebook post, which has been shared more than 82,000 times, contains an identical photo but with a huge statue of the Hindu god Shiva in the cave.
The caption of this post says: “If you believe Shiva, then like above.”
Other versions of the photograph show a statue of Buddha in the same location, for example here on Pinterest.
The cave in the doctored images is actually Heaven's Gate at Tianmen Mountain, in China’s central Hunan province.
Here is an October 2017 Google Maps image of the stairs and cave:
According to the official Tianmen Mountain website, the area is a Level 5a National Tourist Spot and National Forest Park of China. The exact spot featured in the misleading photographs is called the “entrance to Tianmen cave”.
Here is a 2007 AFP Forum photograph taken by Imagine China showing the Tianmen cave:
Here is a Baidu maps photograph of the entrance to Tianmen cave
The actual image of the cave entrance used in the misleading posts has circulated widely online since at least 2016, for example here on a Spanish Google plus account, here on a Turkish Twitter feed, and here on a Hindi-language blog.
Below is a side by side comparison of the misleading images and the original photograph in which key identifying markers -- for example, the locations of people walking up the stairs and a Chinese-language sign in the left hand lower corner of the image -- are identical.
