Big Ben vs Jeddah Tower

Informations

Big Ben is the nickname for the Great Bell of the striking clock in the north end of the Palace of Westminster in London; the name is often extended to refer to both the clock and the clock tower. The official name of this tower in which Big Ben is located was originally the Clock Tower; it was renamed Elizabeth Tower in 2012 to mark the Diamond Jubilee of Elizabeth II, Queen of the uk. The tower was designed by Augustus Pugin at a neo-Gothic style. When completed in 1859, its clock was the largest and most accurate four-faced striking and chiming clock on the planet. The tower stands 315 ft (96 m) tall, and the climb from ground level to the belfry is 334 steps. Its foundation is square, measuring 39 ft (12 m) on each side. Dials of the clock are 23 feet (7.0 m) in diameter. On 31 May 2009, celebrations were held to mark the tower's 150th anniversary.Big Ben is the biggest of the tower's five bells and weighs 13.5 long tons (13.7 tonnes; 15.1 short tons). It was the biggest bell in the United Kingdom for 23 years. The origin of this bell's nickname is open to question; it might be named after Sir Benjamin Hall, who oversaw its own installation, or heavyweight boxing champion Benjamin Caunt.

Four quarter bells chime at 15, 30 and 45 minutes past the hour and just before Big Ben tolls on the hour. The clock uses its first Victorian mechanics, but an electric motor can be applied as a backup. The tower is a British cultural icon recognised all over the world. It is among the most prominent symbols of the uk and parliamentary democracy, and it is often used in the establishing shot of films set in London. The clock tower has been a part of a Grade I listed building since 1970 and a UNESCO World Heritage Site since 1987. On 21 August 2017, a four-year schedule of renovation works began on the tower, which are to include the addition of a lift. In addition, there are plans to re-glaze and repaint the clock dials. With a few exceptions, such as New Year's Eve and Remembrance Sunday, the bells should be silent until the work is completed in 2021.

Jeddah Tower (Arabic: ??? ????), previously called Kingdom Tower (??? ???????), is a stalled construction project of a skyscraper on the north of Jeddah, Saudi Arabia. It is supposed to be the world's first 1 km (3,281 feet ) high building, and the centrepiece and first phase of a development and tourist attraction called Jeddah Economic City.There was steady progress but in January 2018 building owner JEC halted structural concrete work together with the tower about one-third completed because of labour issues with a builder after the 2017--19 Saudi Arabian purge. JEC has said they plan to restart construction in 2020. The design, created by American architect Adrian Smith, who also designed the Burj Khalifa, incorporates many unique structural and aesthetic features. The founder and leader of the project is Saudi Arabian prince Al-Waleed bin Talal, a grandson of Ibn Saud, and nephew of the Kings of Saudi Arabia before him. Al-Waleed is the chairman of Kingdom Holding Company (KHC), which is a partner in the Jeddah Economic Company (JEC), which was formed in 2009 for the development of Jeddah Tower and City.
