Architectural photographer Carlos Ayesta captured these unusual views of Paris by abseiling down the side of skyscrapers.
Carlos Ayesta is a freelance photographer specialising in architecture. He has abseiled from Paris structures such as La Tour Eiffel, La Grande Arche de la Défense, the Center of New Industries and Technologies (CNIT), Tour EQHO and Tour Sequoia.
By dangling from the sides of these buildings, Ayesta wanted to gain a unique perspective of the architecture and the surrounding environment.
"My approach of taking photographs whilst abseiling and from hanging platforms shows the architecture in another dimension," Ayesta told Dezeen.
Ayesta hopes to capture the city, district and buildings in his photographs from a previously unseen perspective. "I can take pictures of hidden thing. No-one on the ground or on top of the buildings can see what I see," he explained.
"I take pictures of towers, offices and homes, and I am able to capture the people working and living within those spaces," he continued. "The window reflections are magical - you can see life and the landscapes within the same frame."
Ayesta told Dezeen he is talking to a company in Tokyo about his next project.
