Recent satellite and tourist photos show construction trucks outside of North Korea's Ryugyong Hotel, indicating that construction is restarting, according to The Daily Mail.
Much confusion and mystery surrounds the 105-story, pyramid-shaped hotel, also known as the "Hotel of Doom."
Construction on the hotel began in 1987, under Kim Il Sung, the founder of North Korea and Kim Jong Un's grandfather.
It was supposed to be finished in the late 1980s, but construction was stopped in the early 1990s because of an economic depression.
An Egyptian company was hired to make some improvements in 2008, and there have been rumors in the last few years that it could open soon, but the hotel's fate remains unknown.
In late July, Pyongyang took walls surrounding the building down, unveiling walkways to the hotel, fueling speculation that construction might start again, according to Fox News.
Below are photos of the hotel, most of which were taken in Spring 2017 and provided by Korea Risk Group, a company billed as the leading provider of risk analysis, news, information and data surrounding North Korea.
Originally slated to open in 1989, the hotel was supposed to have Japanese lounges, casinos, and night clubs.
