The county was created in 1851 and organized in 1861.[3] It is named after the strait between the Door Peninsula and Washington Island. The dangerous passage, known as Death's Door, is now scattered with shipwrecks, and was known to early French explorers and local Native Americans.

Door County is a popular vacation and tourist destination, especially for residents of Wisconsin and Illinois.[4]



The Door County peninsula has been inhabited for about 11,000 years.[5] Artifacts from an ancient village site at Nicolet Bay Beach have been dated to about 400 BC. This site was occupied by various cultures until about 1300 AD.[6]

Door County's name came from Porte des Morts, anglicized as "Death's Door," or the passage between the tip of the Door County Peninsula and Washington Island.[7] It is a common misconception that the name "Death's Door," or "Porte des Morts", arose from the number of shipwrecks associated with the passage. It was instead the result of Native American tales, heard by early French explorers and greatly embellished by Hjalmar Holand that related to a failed raid by the Ho-Chunk (Winnebago) tribe to capture Washington Island from the rival Pottawatomie tribe in the early 1600s.[8]

Prior to and during the 19th century, various groups of Native Americans occupied the area that would become Door County and its islands. 17th century French explorers made contact with various tribes, including Potawatomi living in the Door Peninsula, but by the end of the French rule over the area in 1763, the Potawatomi had begun a move to the Detroit area, leaving the large communities in Wisconsin. Later, some Potawatomi moved back from the lower peninsula of Michigan to northern Wisconsin. Some, but not all Potawatomi later left northern Wisconsin and settled into northern Indiana and central Illinois.[9]

Potawatomi Chief Simon Onanguisse Kahquados, 1919

The Menominee ceded their claim to the Door Peninsula to the United States in the 1836 Treaty of the Cedars following years of negotiations with the Ho-Chunk and the United States government over how to accommodate the incoming populations of Oneida, Stockbridge-Munsee, and Brothertown peoples who had been removed from New York.[10] At the same time, the more decentralized Potawatomi were divested of their land without compensation. Many emigrated to Canada. Reasons for emigrating included an invitation from other Native Americans already in Canada, favorable treaty arrangements, and a desire to avoid the harsh terms of the 1833 Treaty of Chicago. Although not all Potawatomi participated in the Treaty of Chicago, at the time it was Federal policy that any who did not relocate westwards as the treaty stipulated would not be compensated for their land.[11]

Potawatomi Chief Simon Kahquados traveled to Washington, D.C. multiple times in an attempt to get the land back. In 1906, Congress passed a law to establish a census of all Potawatomi formerly living in Wisconsin and Michigan as a first step towards compensation. The 1907 "Wooster" roll, named after the clerk who compiled it, documented 457 Potawatomi living in Wisconsin and Michigan and 1423 living in Ontario. Instead of returning the land, a meager monthly payment was issued.[11] Although Chief Simon Kahquados was unsuccessful he was able to increase public consciousness of Potawatomi history. In 1931, 15,000 people attended his burial in Peninsula State Park.[12]

The 18th and 19th centuries saw the immigration and settlement of pioneers, mariners, fishermen, loggers, and farmers, with the first white settler being Increase Claflin.[13] In the 19th century, a fairly large-scale immigration of Belgian Walloons populated a small region in southern portion of the county.[6] They built small roadside votive chapels, some still in use today.[14] Eagle Bluff Lighthouse was constructed in Peninsula State Park in 1868 on orders from President Andrew Johnson, at a cost of $12,000. It was restored by the Door County Historical Society in 1964, and opened to the public.[15] When the 1871 Peshtigo Fire burned the town of Williamsonville, 60 people were killed. The area of this disaster is now Tornado Memorial County Park, named for the whirlwinds of fire.[16]

In 1941, the Sturgeon Bay Vocation School opened, now it is the Sturgeon Bay campus of Northeast Wisconsin Technical College. A Civilian Conservation Corps camp was established at Peninsula State Park during the Great Depression. In the summer of 1945, Fish Creek was the site of a POW camp under an affiliation with a base camp at Fort Sheridan, Illinois.[17][18][19] The German prisoners engaged in construction projects, cut wood, and picked cherries in Peninsula State Park and the surrounding area.[20]

According to the U.S. Census Bureau, the county has a total area of 2,370 square miles (6,100 km2), of which 482 square miles (1,250 km2) is land and 1,888 square miles (4,890 km2) (80%) is water.[21] It is the largest county in Wisconsin by total area. The county also has 298 miles (480,000 m) of shoreline. Locals and tourists alike refer to the area as the "Cape Cod of the Midwest".[22] The county covers the majority of the Door Peninsula. With the completion of the Sturgeon Bay Shipping Canal in 1881, the northern half of the peninsula, technically became an island.[15] The 45th parallel north bisects this "island," and this is commemorated by Meridian County Park.[23]

Limestone outcroppings of the Niagara Escarpment are visible on both shores of the peninsula, but the karst formations are larger and more prominent on the Green Bay side as seen at the Bayshore Blufflands. Progressions of dunes have created much of the rest of the shoreline, especially on the easterly side. Flora along the shore provides clear evidence of plant succession. The middle of the peninsula is mostly flat or rolling cultivated land. The height of the escarpment made it attractive to development. At the time of its completion in 1999, the 30.5 acre (12.3 ha) Rosière Wind Farm was the largest in the Eastern United States.[24]

Soils overlaying the dolomite bedrock are very thin in the northern half of the county; thirty-nine percent of the County is mapped as having less than three feet (about a meter) to bedrock. Beyond the northern tip of the peninsula, the partially submerged ridge forms the Potawatomi Islands, which stretch to the Garden Peninsula in the Upper Peninsula of Michigan. The largest of these islands is Washington Island. Most of these islands form the Town of Washington.[25]


There are 24 state-defined natural areas in the county.[26] Besides Lake Michigan, there are 25 lakes, ponds or marshes and 37 rivers, creeks, streams, and springs in the county.[27]


Door County, along with nearby Marinette and Delta (see Garden Peninsula) counties, is home to endemic plants and disjunct populations,[28] such as those protected at Hog and Plum Islands, Coffee Swamp, Cave Point County Park, the adjacent Whitefish Dunes State Park, and The Ridges Sanctuary. 25 native orchid species are found at The Ridges.[29] As of 2019, 1201 species and hybrids of vascular plants[30] and 255 unique taxa of mosses, liverworts, and hornworts[31] have been identified in Door County. In 2006, 60 species of aquatic plants or macrophytic algae were found in Clark Lake and nearby upstream.[32] In 2017, 9 species of aquatic plants were found in the Forestville Millpond, also called the Forestville Dam or Forestville Flowage.[33] The U.S. Potato Genebank just north of Sturgeon Bay is the world's largest living collection of wild and domesticated potatoes.[34] As of 2019, 243 species of mushrooms and other macrofungi have been identified north of the canal,[35] with 326 species for the county as a whole.[36] As of 2019, 243 species of mushrooms and other macrofungi have been identified north of the canal.[37]


From 1971 through 1976, 11 species of small mammals were found at Toft Point,[38] the Newport State Park Mammals Checklist has 34 species,[39] and in 1972 44 mammals were listed for the entire county.[40] In 1992, six amphibians and eight reptiles were found in and around Potawatomi State Park.[41] As of 2018, 166 species of birds have been confirmed to live in Door County, excluding birds seen which lack the habitat to nest and must only be passing through.[42] In 1999, the Wisconsin Natural Heritage Inventory listed 24 aquatic and 21 terrestrial animals in Door County as being "rare."[43] In particular, Kangaroo Lake State Natural Area has the largest breeding population of the endangered Hine's Emerald Dragonfly in the world.[44]

Air pollutionEdit

2016 HYSPLIT map

Most air pollution in Door County comes outside the county. This map shows how air travels to the pollution monitor in Newport State Park.[45] Because the monitor at Newport State park is near the shore, only the red lines (which show the lower air currents) meaningfully depict the path of ozone to the monitor. Unfortunately, as shown on the map, these lower air currents carry polluted air from major urban areas. But further inland, the air from higher up mixes more, so all color lines are significant when tracing the path of air pollution further inland. Fortunately, these higher air currents (shown in green and blue) blow in from cleaner, mostly rural areas.[46]


Migrant Worker Housing (March, 2011) Because the cost of living in Door County is high compared to the limited income many tourism-industry jobs provide, temporary workers are often hired, both domestic and foreign. Workers come from as far away as Scandinavia or South Africa.

Hjalmar Holand, an Ephraim resident, promoted Door County as a tourist destination in the first half of the 20th century. Leading a committee to protect and promote historically important sites, a series of county parks were established. Since then the tourism industry has grown. Although Door County has a year-round population of about 28,000, it experiences an influx of tourists each summer between Memorial Day and Labor Day. Most businesses are targeted to tourism and operate seasonally. In the summer, the population of Door County is much larger.[47] The majority of tourists and summer residents come from the metropolitan areas of Milwaukee, Chicago, Madison, Green Bay, and the Twin Cities.[48] The area has been called "the Cape Cod of the Midwest."[48] Tourism supports a Bohemian arts community from Sturgeon Bay northward.

Door County is home to five state parks: Newport State Park, northeast of Ellison Bay; Peninsula State Park, east of Fish Creek; Potawatomi State Park, along Sturgeon Bay; Rock Island State Park, off the tip of the Door Peninsula; and Whitefish Dunes State Park, along Lake Michigan.[49] A local land trust operates 14 privately owned parks open to the public,[50] and thousands of acres of other privately owned land are open to the public for hunting, fishing, hiking, sight-seeing and cross-country skiing under the Managed Forest Program.[51]

Door County has ten lighthouses. Most were built during the 19th century and are listed in the National Register of Historic Places: Baileys Harbor Range Lights; Cana Island Lighthouse; Chambers Island Lighthouse; Eagle Bluff Lighthouse; Pilot Island Lighthouse; Plum Island Range Lights; Pottawatomie Lighthouse; and Sturgeon Bay Canal Lighthouse. The other lighthouses in the county are: Baileys Harbor Lighthouse; Sherwood Point Lighthouse; and the Sturgeon Bay Canal North Pierhead Light.[52]

Door County has a history of cherry and apple growing that dates back to the 19th century.[53] Farmers were encouraged to grow fruit on the basis of the relatively mild climate on the peninsula. This is due to the moderating effects of the lake and bay on nearby land temperatures. U-pick orchards and fruit stands can be found along country roads when in season, and there are two frozen cherry processors.[54] However, the cherry business has declined since peaking in the late 1960s[55] due to lack of migrant labor and a difficulty in finding local help, the closing of a major cannery, unpredictable harvests, and better growing conditions to the east in the fruit belt, such as the nearby Traverse City area.[56]

Scandinavian heritage related attractions include fish boils,[57] The Clearing Folk School, two stave churches,[58] and Al Johnson's Swedish Restaurant, which features goats on its grassy roof.

Door County also has businesses which produce alcoholic beverages,[59] and as a result the county became part of a federally designated wine grape-growing region in 2012. In order to encourage more tourism, Ephraim residents passed referenda in 2016 to allow beer and/or wine sales within the village. Prior to this, Ephraim had been the last dry municipality in the state.[60]


Major highwaysEdit



  • Washington Island is served by two ferry routes. The first route is to take a 30-minute ferry ride from the Door Peninsula to Detroit Harbor on the island from a freight, automobile, and passenger ferry that departs daily from the Northport Pier at the northern terminus of Wisconsin Highway 42. The second route is a passenger-only ferry that departs from the unincorporated community of Gills Rock on a 20-minute route.[61]
  • Rock Island State Park is reachable by the passenger ferry Karfi from Washington Island.[62] (During winter Rock Island is also accessible via snowmobile and foot traffic.)
