1. World’s Tallest Man-Made
Structures
By Samarth Asija

2. Burj Khalifa , known as Burj Dubai before its
inauguration, is a skyscraper in Dubai, United
Arab Emirates. It is the tallest artificial structure
in the world, standing 829.8 m (2,722 ft).
Burj Khalifa was designed to be the
centerpiece of a large-scale, mixed-use
development that would include 30,000 homes,
nine hotels (including The Address Downtown
Dubai), 3 hectares (7.4 acres) of parkland, at
least 19 residential towers, the Dubai Mall, and
the 12-hectare (30-acre) man-made Burj
Khalifa Lake.
The decision to build Burj Khalifa is reportedly
based on the government's decision to
diversify from an oil based economy to one that
is service and tourism based. According to
officials, it is necessary for projects like Burj
Khalifa to be built in the city to garner more
international recognition, and hence
investment.

3. Tokyo Skytree is a broadcasting,
restaurant, and observation tower in
Sumida, Tokyo, Japan. It became the
tallest structure in Japan in 2010 and
reached its full height of 634.0 metres
(2,080 ft) in March 2011, making it the
tallest tower in the world, displacing the
Canton Tower, and the second tallest
structure in the world after Burj
Khalifa(829.8 m/2,722 ft).
The tower is the primary television and
radio broadcast site for the Kantō
region; the older Tokyo Tower no
longer gives complete digital terrestrial
television broadcasting coverage
because it is surrounded by high-rise
buildings.

4. The KVLY-TV mast (formerly the KTHI-
TV mast) is a 2,063 ft (628.8 m) tall
television-transmitting mast in Blanchard,
Traill County,North Dakota, United States,
used by Fargo station KVLY-TV channel
11. Completed in 1963, it was the tallest
structure in the worlduntil succeeded by
the Warsaw radio mast in 1974; that mast
collapsed in 1991, making the KVLY-TV
mast again the tallest structure in the
world until the Burj Khalifa overtook it in
2010. It remains the fourth-tallest
structure in the world (since the
construction of theTokyo Skytree and the
Shanghai Tower), the tallest structure in
the western hemisphere, and the tallest
radio mast in the world.

5. The Abraj Al-Bait Towers, also known as the
Makkah Royal Clock Tower Hotel, is a
government-owned megatall building complex in
Mecca, Saudi Arabia. These towers are a part of
the King Abdulaziz Endowment Project that strives
to modernize the city in catering to its pilgrims.
The central hotel building has the world's largest
clock face and is the third tallest building and
fourth tallest freestanding structure in the world.
The building complex is metres away from the
world's largest mosque and Islam's most sacred
site, the Masjid al-Haram. The developer and
contractor of the complex is the Saudi Binladin
Group, the Kingdom's largest construction
company. The complex was built after the
demolition of the Ajyad Fortress, the 18th-century
Ottoman citadel which stood atop a hill
overlooking the Grand Mosque. The destruction of
the fort in 2002 by the Saudi government sparked
Turkish and international outcry.

6. VLF transmitter Lualualei is a facility of the United States Navy
near Lualualei, Hawaii transmitting orders to submerged
submarines in the very low frequency (VLF) range. VLF
transmitter Lualualei, which operates under the callsign NPM on
21.4 kHz and 23.4 kHz, uses as antenna two guyed masts, each
458.11 metres (1503 feet) tall. Both masts, which were built in
1972, were not only the tallest towers in the Western
hemisphere at the time, used for military purposes, they are
also the tallest towers used for long wave transmissions in the
Western hemisphere and since the collapse of Warsaw Radio
Mast perhaps the tallest structures electrically insulated against
ground.
Both masts are umbrella antennas. They are fed with the radio
power to be radiated by an overhead wire, which is fixed at one
end with the mast and at the other end to a small mast near the
helix building. As this small mast is grounded, the feeder is
attached to this mast with an insulator in the span field.

7. The Petronas Towers, also known
as the Petronas Twin Towers
(Malay: Menara Petronas, or
Menara Berkembar Petronas), are
twin skyscrapers in Kuala Lumpur,
Malaysia. According to the Council
on Tall Buildings and Urban Habitat
(CTBUH)'s official definition and
ranking, they were the tallest
buildings in the world from 1998 to
2004 and remain the tallest twin
towers in the world. The buildings
are a landmark of Kuala Lumpur,
along with nearby Kuala Lumpur
Tower.
