There are three buildings from the 19th century still standing on the island: The Schoolhouse, the Humphrey farm house, and the Stone House. The Stone House is located in the northeast corner of the island, while the Humphrey house and Schoolhouse are both in the middle of the island, closer to the northern shore.
Schoolhouse The
Grenadier Island Schoolhouse is located in the middle of the island. It has a single room with an outhouse situated behind it. In the early 20th century it had around 13 students. It was added to the
National Register of Historic Places in 2012.
Humphrey farm house The Humphrey farm house, also known as the "Carbide House", was a two-story home with a basement and an attic. The house has been abandoned for many decades, and has been gradually falling in upon itself for many years (as of 2014). The walls of the home eventually caved in at an unknown date. ==References==
