fresnel lens

this morning we visited another lighthouse at Rimouski. We were able to go up this one on a guided tour which happened to only have the two of us on. Maybe others had thought twice about climbing what is the second highest lighthouse in Canada ! We'd previously stayed near the tallest one at Cap de Rosiers but it was closed for  renovation. Later we stopped of at the lovely town of Kamourska for lunch then drove on to Quebec city. 
My main image is from inside the lighthouse looking up at the lens and extra a view of the lighthouse.
