Ghadames - also known as the 'pearl of the desert'.

It's one of the most ancient pre-Saharan cities and the traditional architecture of its Old Town is recognised by UNESCO as a World Heritage Site.

But the beautiful buildings have been damaged and it is now a worringly entry on the World Heritage in Danger list.

And the threat seems to be coming from above.

"The fall of very heavy rain led to some collapses around the town and inside places," says Ibrahim Bashier, Director of the International Cooperation and Training of Historic Cities Management.

"These collapses are in fact caused by several reasons, and the main reason is the Old Town has been abandoned by residents who used to protect against water, rain water."

The area was not updated with basic modern utilities, such as electricity, for fear of damaging the buildings' unique character.

But that has meant that people are unwilling to live there and keep the homes in good condition.

Bashier says reports have been completed which he hopes will bring support for maintanence in the "near future".

Libya's unstable security situation means UNESCO has been unable to enter Ghadames for several years.

What was once a favourite international tourist destination is now visibly crumbling.

Libyan officials have appealed to UNESCO to intervene, either by helping to repair the damage or taking steps to reduce the danger of further problems.

"It can be supported by sending technicians or even be supported by consultations, and this of course will have a big role in removing the site from the danger list," says Nader Al-Kadiki, a resident of Ghadames.

The Old Town of Ghadames in one of five Libyan sites on the UNESCO list of World Heritage in Danger. They were entered onto the list in 2015.
