The Bell Rock Lighthouse is the oldest surviving sea-washed lighthouse. This bell tower is one of the Seven Wonders of the Industrial World. It is built on the Bell Rock, also known as Inchcape which is located in the North Sea off the coast of Scotland. The construction of the lighthouse had to be done here as the rock was just below the surface of water and is not visible except at low tide. This has caused many accidents at this spot in the past.
The lighthouse has been constructed so well and the masonry standards were so high that they have not been replaced or adapted since the last 200 years. The rock on which the tower is constructed has been named after a warning bell was installed on it in 14th century. However, only one year later a Dutch pirate removed the bell.
The lighthouse was built by Stevenson between 1807 and 1810 after the furore that rose in the Parliament after a warship HMS York disappeared in the sea in 1804. Earlier as well, the rock had claimed of numerous sailors and hundreds of ships sank in the sea. Many problems were faced by the people during the construction of the light house due to the submerged nature and weather hazards that made it a difficult task.
