Lighthouse Base, Prince Shoal

Lighthouse Base, Prince Shoal


Built at Davie then transported to Prince Shoal, four miles off Tadoussac, the spool-shaped caisson was built for a lighthouse base to provide navigational assistance in one of the most dangerous shals in the St. Lawrence River. The tapered base was filled with 8,000t of crushed rock into which cement grout was pumped.
