The tower starts as a square then gradually goes into an octagon.
Wood trim decorates part of the tower and adds a unique touch to the gothic-looking light station.
The light station was built in 1881 and is built with the same Norman Gothic style as many churches and town houses of that period. When an automatic timed light was installed in 1921, keepers were no longer needed on the island. The light was finally fully automated in 1933. Sand island was also a lighthouse that had many neighbors. These people included fishermen, mariners, and the wives of all the working men.
