# Çamlıca Tower

Küçük Çamlıca TV & Radio Tower (Turkish: Küçük Çamlıca TV-Radyo Kulesi), or simply Çamlıca Tower, (Turkish pronunciation:) is a telecommunications tower with observation decks and restaurants on Little Çamlıca Hill in Üsküdar district of Istanbul, Turkey.
The total height of the tower is 369 metres (1,211 ft), 221 metres (725 ft) of which is a 49-storey reinforced concrete structure with 18 metres (59 ft) below ground. The height of the tower's steel antenna is 168 metres (551 ft). With a total height of 587 metres (1,926 ft) above sea level, it carries the title of the highest structure in Istanbul.
The structure was chosen by then prime minister Recep Tayyip Erdoğan after the Çamlıca Hill TV & Radio Tower Idea Project, which was opened by Istanbul Metropolitan Municipality in 2011. Construction started in late 2016 and finished four years later in September 2020. However, the project was set to be completed by the end of 2019. It was inaugurated on May 29, 2021.
After the tower was put into service, other antennas and antenna towers such as Çamlıca TRT Television Tower were either removed or demolished.

## Architectural design

The tower is designed by Melike Altınışık Architects (MAA) firm, founded by Melike Altınışık after she left Zaha Hadid Architects. The building itself is a single piece structure, which was inspired by the Tulip flower; a symbol for the Turks during the Ottoman period. The main axis of the tower includes the roots and feeder stem of the tulip. The viewing terrace and restaurant floors resemble a tulip bud that hasn't bloomed yet.
Panoramic elevators rising from the ground floor to the top floor, are located on both sides of the main building. These elevators symbolize the Bosphorus, which both separates and integrates the Asian and European continents.

## General contractor

The construction project was awarded to Saridaglar Construction following a public bidding procedure by the Turkish Ministry of Transport and Infrastructure.
Saridaglar's scope included:
* Civil Works
* Construction Works
* Architectural Works
* MEP Works
* Landscaping Works.
This was one of the rare fast-track projects in Turkey. Due to the fast-track nature of the contract and complexity of construction methodologies, the project was subject to budget and schedule alterations.

## Structure specifications

The tower is built in concrete on a 18 m (59 ft) deep foundation. A steel mast of 168 m (551 ft) height for radio and television transmission is mounted atop the 203.5 m (668 ft) high concrete tower. The total height of the tower is 369 m (1,211 ft) with its top standing 587 m (1,926 ft) above main sea level. It is the highest structure in Istanbul.
