Melike Alt?n???k Architects' 369-metre-high Çaml?ca TV and Radio Tower has almost completed in Istanbul, with only the engineered facade left to install.
Construction began on the supertall telecommunications tower in 2011, and is due to finish later this year. When finished, it will be the highest structure above sea level in the city.

With staggered, elliptical levels near the top, the tower's geometry is designed to change from different perspectives across the Turkish capital.
As well as being a key piece of infrastructure for Turkey's ministry for transport and communications, the structure will host a series of visitor attractions.
The top 15 levels will house observation decks and a restaurant offering 360-degree views over the city, which sits on the border of Europe and Asia.
The observation decks will sit at 148 and 153 metres, while the restaurant will host diners at 153 and 175 metres in the air.
A panoramic lift will transport the expected 4.5 million visitors a year up the tower, which will also have a library and exhibition spaces situated in its base.

When complete, the Çaml?ca TV and Radio Tower will have capacity for 125 broadcasting transmitters.

Levels of the tower have been lifted up in phases and attached to the concrete core. Each level is 4.5 metres high and weighs between 1,000 and 1,200 tonnes.
Four of the eight construction phases are now done, with the final four phases to lift up the 103-metre facade scheduled to complete by autumn 2019.
