The
famous
____________________
Tower
of
Pisa
is
the
____________________
tower
of
the
cathedral
in
the
____________________
of
Pisa
,
in
Italy
.
Its
____________________
is
55
.
8m
,
it
has
8
____________________
and
there
are
294
____________________
to
the
top
.
Construction
____________________
in
1173
and
it
took
200
years
to
____________________
.
The
architect's
____________________
is
still
unknown
,
but
we
do
know
that
he
designed
the
tower
to
be
____________________
.
After
the
third
____________________
was
built
,
the
tower
started
to
____________________
,
mainly
because
its
____________________
was
shallow
?
only
3
metres
?
and
in
weak
soil
.
The
Pisans
stopped
____________________
twice
?
for
almost
100
years
each
time
?
because
they
were
busy
____________________
battles
with
other
Italian
cities
!
In
1372
,
the
tower
was
____________________
and
seven
bells
were
____________________
,
one
for
each
note
of
the
____________________
scale
.
Over
the
years
,
there
have
been
many
____________________
to
straighten
it
,
or
halt
the
____________________
.
This
was
not
as
____________________
as
it
seemed
.
Some
of
those
attempts
had
exactly
the
opposite
____________________
:
the
tower
sank
even
further
into
the
____________________
!
The
latest
attempt
was
completed
____________________
2001
and
took
ten
____________________
.
The
tower
has
been
declared
____________________
for
at
least
another
300
____________________
.
