Tank Cottage is located within Heritage Hill State Historical Park in Green Bay, Wisconsin.

After the war, Porlier swore allegiance to the United States and in 1820 became chief justice of the Brown County court of the Michigan Territory.

[2] In 1850, Norwegian Moravian missionary Nils Otto Tank purchased the cottage and large tract of land along the Fox River.

His wife, Caroline van der Meulin, covered the pièce-sur-pièce à coulisse work with clapboard and lived there until her death in 1891.

In 1908, the cottage was in danger of demolition as the city became more industrial, so it was moved from its original location on 8th Street along the river to Tank Park.
