Time was when the best mode of inland transport was
by water. Where rivers did not exist, or did not connect major towns,
man reshaped the land by cutting canals. Where the ground level fell
drastically, locks were put in place to allow the passage of boats from
higher to lower ground, and vice versa. As time went by, improvements in
road construction and later, with the invention of the railway train,
the canals declined in importance. With the advent of automobile powered
societies, many canals have been simply abandoned.
History of the canals
Britain was once the workshop of the world. Textiles, liquor and the
machinery led the march towards industrial scale production. The
cutting of canals put coal and other minerals within reach of the
industrial centers arising. Imported raw materials made their way
inland to the growing hubs of factories everywhere. Scotland was no
less affected. Its largest towns of Edinburgh and Glasgow were
booming with whisky and shipbuilding. The Forth and Clyde and Union
Canals linked these two cities and managed the gradient difference
with a series of 11 locks.
As traffic declined,
the canals ceased to be used for navigational purposes. With no long
term plans and maintenance halted, the canals were expected to die
out slowly and dry up into small pools of water. That is, up until a
national body, the Millennium Commission, decide to take up the
challenge to rehabilitate the canal and restore it to proper
functionality. The Millennium Commission was set up specifically to
apply funds from the National Lottery to fund projects celebrating
the end of the 2nd Millennium and the start of the third. Proposals
were solicited and the restoration of this canal, linking the two
main estuaries of Scotland was made to the Commission and accepted.
The two canals had a water level gap of 115 feet. To bridge this
gap, the organization responsible, British Waterways, intended to
have a radical solution in preference to traditional locks. A
revolving lift capable of lifting 600 tonnes of water in a
rotational motion created a dramatic structure which stands out in
the Scottish countryside.
Dubbed a stunning piece
of working sculpture, the Falkirk Wheel presents a different image
when seen from different vistas. From far away, the sharp spines
rising in the sky appear to look like the bones of a giant whale
beached inland. From within the lift, the arches look like a tunnel
enveloping the pool of water in which the boat would slide. The
impression of a canal which ends in mid-air is also somewhat
disconcerting. While it is gracefully beautiful, the underlying
objective of the design is efficiency using just 1.5 kW of power
to move two boats plus water of about 600 tonnes in 15 minutes. A
system of cogs turns the caissons containing the water and boats
precisely so that the boats remain upright throughout the transfer
process.
You can take a trip from the wheel up the
Union Canal. You can start with an exhibition at the Visitor Centre
admission free that gives you more information about the design
and construction of the structure. Then the boat trip begins. You
start from the basin, slide into the gondola which holds the boat
and water, and the whole thing begins its turn up. You can take in
the panoramic view of the Scottish countryside on the ascent up. The
ride then sails along the aqueduct and the 180 metre long
Roughcastle Tunnel. This is actually under the historic Roman
fortification, called the Antonine Wall. The trip is a round trip
and brings its passengers back for a descent experience on the
wheel.
