Rockefeller Center, originally known as Radio City is a complex of buildings developed in the midst of the Great Depression.
Initially the complex consisted of 14 buildings, the 70 story RCA building being the tallest.
The area where the Rockefeller Center is located was originally
planned as the new location for the
Metropolitan Opera.
The original area, between 48th and 51st streets, Fifth
and Sixth avenue, was a red-light district owned by
Columbia University.

John D. Rockefeller Jr. leased
the area on behalf of the Metropolitan Opera.
The design
of the complex was done by the architect Benjamin Wistar
Morris. When the Met abandoned the project after the
1929 stock market crash, Rockefeller came up with a
plan for a corporate complex to house the new radio
and television corporations. Radio City was born.
One
of the first buildings completed was the
RCA building,
which served as the headquarters of the Radio Corporation
of America. The tower, clad in Indiana limestone, is
at 70 stories and 256 meter / 850 ft the tallest of the complex.
Its design by Raymond Hood - also known from

the
American
Radiator Building in New York, the former
McGraw-Hill
building in New York and the
Tribune
Tower in
Chicago -
was the basis for all future buildings at the Rockefeller.
To lure tenants during the Depression, all efforts were
made to ensure efficient use of the available floor
space. Thanks to the setbacks each office was assured
of natural light. Other assets were fast elevators,
air-conditioning and excellent underground connections
to the subway.
The RCA building is now also
known as 30 Rockefeller Plaza or GE Building.
The Rockefeller Center features an
observation deck atop the GE Building with panoramic views of
Central Park and the
Empire State Building. When the former RCA building opened in 1933 it featured

a roof terrace designed as the deck of an ocean liner. Ventilation pipes were shaped as a ship's chimneys and visitors could relax in deck chairs. The observation deck remained open until 1986. By then the number of visitors had dropped while costs increased. At the same time the expansion of the popular Rainbow Room restaurant on the 65th floor cut off the elevator access to the roof, leading to the deck's closure.
Fortunately the observation deck reopened again in November 2005, finally

giving the nearby
Empire State Building's observatory some competition. After a renovation of some 75 million dollars, the art-deco style observation deck, promoted as the '
Top of the Rock' can be visited once again; only the deck chairs have disappeared.
A separate entrance at West 50th Street leads to the elevators. In the elevator, important historic events since 1933 are projected on the elevator's transparent roof.
There are in total three levels open to the public, including the roof terrace. The first is on the 67th floor and is completely covered.

The observation deck on the 69th floor has glass windshields while the 70th floor is completely open to the elements, offering visitors a fabulous 360 degree view.
By
1940 Radio City, which became known as Rockefeller
Center consisted of 14 buildings, located around a

central
sunken plaza, the Lower Plaza. The plaza, best known
for its very popular skating rink, is connected to Fifth
Avenue via a pedestrian street decorated with statues
and flowers. It is known as the
Channel Gardens,
as it is flanked by the British Empire Building and
La Maison Française. From the Channel Gardens
you have a nice view on the sculpture of Prometheus
and the GE building. Another important building in the
Rockefeller Center is the
Radio City Music Hall.
When built, it was the largest indoor theater in the
world

with
a seating capacity of around 6000. Guided tours give
you the opportunity to catch a glimpse of the spectacular
Art Deco interior.
The Rockefeller Center, known as the 'city in the city'
is an exceptional example of civic planning. All buildings
share a common design style, Art Deco, and are connected
to each other via an underground concourse, the Catacombs.
The complex is nevertheless well integrated in the City,
especially along
Fifth Avenue. In 1959 and the early
seventies, the Rockefeller Center was extended with
5 additional buildings along sixth Avenue.
