The
structure
of
the
tower
is
unconventional,
based
on
a
triangle
whose
corners
go
up
in
steel
columns,
consisting
of
three
tubes
with
a
double
steel
wall,
filled
with
concrete.
They
support
nine
'pods'
and
three
decks
for
transmitting
equipment.
One
of
the
three
pillars
extends
considerably
higher
than
the
others,
providing
both
the
necessary
height
for
radio
antennas
and
the
structure's
rocket
and
gantry
appearance.
In
its
time
it
was
a
unique
technology,
which
authors
have
patented.[citation

The
tower
stands
216
metres
(709
feet)
high,
with
the
observatory
at
93
metres,
the
hotel
room
at
70
metres,
restaurants
(with
a
capacity
of
180
people)
at
66
metres.
Three
elevators
transport
passengers
at
a
speed
of
4
m/s.[2]
Three
of
the
pods,
positioned
directly
beneath
the
decks
at
the
top,
are
used
for
equipment
and
are
inaccessible
to
the
public.
The
remaining
six
pods
are
open
to
visitors,
providing
a
panoramic
view
of
Prague
and
the
surrounding
area.
The
lower
three,
approximately
half-way
up
the
length
of
the
pillars
at
63
metres
(207
feet),
house
a
restaurant
and
café
bar.
Construction
of
the
tower
cost
$19
million.
It
weighs
11,800
tonnes
and
is
also
used
as
a
meteorological
observatory.
It
is
a
member
of
the
World
Federation
of
Great
Towers.
