(Imperial
Towers) - Six lighthouses where
built in the Great Lakes Region with this type of architecture know as the "Imperial" Tower.
In the mid-19th century, obsolete navigational aids were keeping the
British North America from strong economic development. The Bruce
peninsula opening for settlement in the mid-1850's, the United States
starting a free trade agreement with Canada in 1854 and the opening of
the Sault Ste. Marie Canal in 1855 were creating a major need for better
aids to navigation through Georgian Bay and Lake Huron. Lobbying by
Montreal's Canadian Shipping magnate, Hugh Allan, along with Admiralty
put a change to that by 1857. A (3) year construction program was
started with all material and construction expenses provided by Great Britain.
A total of $222,564 was spent for construction of all six lighthouses
with the tall, conical, limestone towers built to withstand the
elements, far surpassing the standards of the 1850's both structurally
and financially.
Lighthouse
History : At
Point Clark a rocky shoal extends approximately 2 miles (3.2 km) offshore, directly in line with vessels traveling the
coastline. This hazard was marked by locals with a simple lantern hung
from a pine tree at night, thus the story behind the areas original name
of "Pine Point". It was later renamed Point Clark after
families settled in the area from Clark Township near Toronto, Ontario.
The
construction of a permanent "Imperial Tower" lighthouse was started here in 1855, supervised by John Brown.
In 1859, the Argand lamp and Second Order Fresnel lens began exhibiting a revolving white
beacon. The lens focal plane of 87 feet above Lake Huron is visible for
approximately 15 miles (26.5 km). The characteristics
of flashing once every thirty seconds, easily distinguishes her from Goderich
to the South and Chantry Island to the
North as both of these lights have a fixed beacon.
Constructed of
limestone from nearby Inverhuron and Kingston, the base measures 6 feet thick
tapering up to the lantern. The upper part of the tower is made of
granite, supporting the cast iron lantern room base plate. The (12) sided cast iron
lantern is capped
with a red domed roof which has bronze "lion heads" around the
perimeter, common to the "Imperial Towers". These decorative "lion
heads" worked as spouts for the internal troughs that direct condensation on the inside of the
lantern room ceiling to the outside of the tower. The original use of
sperm whale oil had a need for this, with every gallon of oil burned, a
quart of condensation was created. In the winter months, this
condensation would freeze on the inside of the glass surrounding the
lantern. The keeper would then have to regularly scrape it of so the
light would remain clearly visible.
Though only a short distance away, a
tunnel runs from the tower to the two story keeper's house. This was
done to allow the keeper to easily tend to the light, even during the harshest
of weather experienced along the Eastern shore of Lake Huron. The lighthouse was tended by keeper's until being automated in the
1960's.
This is a beautiful Light overlooking the
rocky shore of Lake Huron, and is a Canadian National Historic Sight
since 1967. The lighthouse can be toured for a nominal fee. A Maritime/Lighthouse museum is
operated by the Township of Huron and open in the summer months from
June through Labor Day, 10:00 a.m. till 5:00 p.m. daily. Also a very nice public beach is within walking
distance.
