Long Tail Point is a sand bar lying at the southern end of the bay; as it lies adjacent to the channel into the city of Green Bay, a lighthouse was constructed in 1848.

The structure was built from fieldstone collected at Bay Settlement on the opposite shore,[3] and was originally lit with an array of oil lamps.

[2] These lamps were replaced with a Fresnel lens in the 1850s,[2] but soon the light was surrounded by water, and it was abandoned in 1859 in favor of a new house a short distance to the north.

[2] The new lighthouse was an integral frame dwelling with the old lantern placed on its roof; it employed a fourth order Fresnel lens.

[2] The second house was sold to a private interest on the understanding that it would be moved; however, during the attempted relocation, the structure fell through the ice and was destroyed.
