#Louisbourg lighthouse was built by the French in 1734 of fieldstone, also known as rubble stone - rough, unhewn rocks set in mortar, but not laid in regular courses. The lighthouse had a slate roof.

While the tower was made of stone, the frame for the lantern was made of wood and it caught fire and was destroyed in 1736. A new lantern was built and finished in 1738. It was designed to be fireproof – it had 6 pillars of cut stone which supported a brick roof.

The lighthouse stood until 1758 when it was destroyed during a British attack on #Louisbourg.
(After capturing the fort, the British wanted to make sure it could not be used by the French again, so miners tunneled under its defenses and set off explosives...

...Some of its cut stone was reused in buildings in #Halifax and #Sydney. For example, St. George's Church in Sydney was partly built with stone from #Louisbourg. It was built between 1785 and 1791 and was Sydney's first building.)

A new lighthouse was built of wood in 1842 but it burned to the ground in 1922.
The lighthouse that stands today was built in 1923-24 and is made of concrete.

Concrete is a mixture of aggregate (sand, gravel or crushed stone) and paste. Today, the paste used in most concrete is portland cement and water. Cement has been manufactured in #Brookfield, #NS, for over a half century.

The #Louisbourg lighthouse sits on Precambrian igneous rocks created from ash spewed into the atmosphere by volcanoes.
