Grosse Ile Township is a civil township in Wayne County in the U.S. state of Michigan. A Downriver suburb of Detroit, Grosse Ile Township consists of multiple islands in the Detroit River (the largest of which is Grosse Ile), roughly southwest of downtown Detroit. As of the 2020 census, the township had a population was 10,777.

Named by French explorers in 1679, Grosse Île means "Big Island". Later taken under British rule after 1763, the island was not settled by European Americans until after the United States achieved independence in the American Revolutionary War. Grosse Ile Township was organized in 1914 after it split away from Monguagon Township.

Geography

According to the United States Census Bureau, the township has a total area of , of which is land and (50.72%) is water.

Grosse Ile is the largest island on the Detroit River. The township of Grosse Ile is composed of twelve islands, although the community is most often identified with the main island (which residents simply refer to as "The Island"). Grosse Ile's main island is technically composed of two islands. Grosse Ile Township is one of only seven municipalities in the state of Michigan to consist entirely of islands, including St. James Township, Drummond Township, Bois Blanc Township (in northern Michigan, not to be confused with the nearby Bois Blanc Island, which is in Canada), Mackinac Island, Peaine Township, and Sugar Island Township.

The tip of the main island's northern section is named Hennepin Point in honor of the 17th-century French explorer Father Louis Hennepin. It is uninhabited and separated from the remainder of the northern section by an unnamed canal that cannot be navigated in a power boat.

The southern section of the main island is separated from the northern section by the Thorofare Canal, which runs on a diagonal course from east to west connecting the main channel of the Detroit River with the Trenton Channel of the river. The southern section of the main island is connected by bridges to Elba Island, Meso Island (also known as Upper Hickory Island), Hickory Island, and Swan Island, which are all inhabited.

Not far from the shoreline of the main island in the river lie Calf Island, Celeron Island (charted as Tawas Island), Dynamite (also known as Powder House Island), Fox Island, Stony Island, and Sugar Island, which are all uninhabited. Stony and Celeron are owned by the Michigan Department of Natural Resources. Calf Island is owned by the U.S. Fish and Wildlife Service as a part of the Detroit River International Wildlife Refuge. The other islands are privately owned. The low-lying Mamajuda Island is off the northeastern tip of Grosse Ile and is visible only during times of low water level.

Two bridges connect the main island to the mainland of Michigan. The bridge on the north end of the island is called the Grosse Ile Toll Bridge (off-white color). The bridge on the south end of the island is officially named the Wayne County Bridge (light green in color), but is commonly called the "Free Bridge" by locals.

History Founding and early times The Potawatomi occupied areas of the island, which they called Kitcheminishen, for a long period prior to European encounter. They were one of the tribes in the Council of Three Fires.

The flags of three nations—France, England, and the United States—have flown over Detroit and Grosse Ile since the first French explorers visited the island during the late 17th century. The early French explorers named the island as la grosse île—the "big island" in French. Father Louis Hennepin, a Catholic priest and missionary, accompanied fellow French explorer René-Robert Cavelier, Sieur de La Salle in 1679 on the ship Le Griffon in exploring the Great Lakes. The Sacred Heart Roman Catholic Church on Grosse Ile says that Father Hennepin came ashore and said mass at a location on the east shore of the island near the present site of St. Anne's Chapel. No record exists of this event, but Father Hennepin wrote in his journals about the fruit orchards and wild animals on Grosse Ile, showing he was here. The north end of Grosse Ile is named Hennepin Point in his honor.

French explorer Antoine de la Mothe Cadillac and his convoy of 25 canoes sailed down the Detroit River and camped on the shore of Grosse Ile during the evening of July 23, 1701. On the morning of July 24, Cadillac returned upriver and landed ashore, where he claimed French possession of the territory under the authority of King Louis XIV. This site is in present-day Detroit, near the present intersection of West Jefferson and Shelby streets.

Grosse Ile maintained its own name and identity as a community through the 18th century. The British established control of the island and present-day Michigan in 1763 after their victory in the French and Indian War. They anglicized the spelling to "Grosse Isle".

Although the Potawatomi, like most Native Americans, did not have the same sense of property ownership as did Europeans and Americans, they considered the island to be part of their ancestral lands. On July 6, 1776, they deeded the island to brothers Alexander and William Macomb, brothers from Albany who had become leading fur traders and merchants in Detroit, partly from selling supplies to the British at Fort Detroit and the local Indian Department. They are considered to be the founders of the European-American community on the island.David B.

Settlement to present Settlement started in the 19th century. At least three homes still standing on the island were built during this period by a descendant or relative of the Macomb brothers. The Rucker Homestead, the oldest structure in use on Grosse Ile, has portions that date to 1816. The front structure was added by John Anthony Rucker in 1835. The Rucker-Stanton House on West River Road was built in 1848 by the great-grandson of William Macomb. The Wendell House on East River Road was built in the late 1860s by John Wendell, who married a granddaughter of William Macomb.

Westcroft Gardens, a Michigan Centennial Farm located on West River Road, is operated by descendants of the Macombs. Westcroft, which is open to the public, features a nursery well known for growing and selling hybrid azaleas and rhododendrons. Westcroft is one of the oldest farms in Michigan still owned by the same family. Most of the original buildings at Westcroft Gardens are still standing and well preserved.

Macomb Street of the central business district of Grosse Ile was named in honor of Alexander and William Macomb. A monument commemorating the day that the tribal chiefs and elders signed the deed to the Macomb brothers is located at the foot of Gray's Drive and near the shoreline of the Detroit River. The original deed, which was written on parchment, is stored in the Burton Historical Collection at the Detroit Public Library.

Trenton Channel and boating

Boating has been both a means of transportation and recreation since the first residents lived on the island. Native Americans used canoes to travel between Grosse Ile's islands and the mainland in Michigan and Canada. Early European settlers primarily used sail-powered vessels to travel to and from the islands.

By the late 19th century, Grosse Ile was known as a popular destination for recreational boaters. It was also served by steamboats operating from Detroit and small towns along the river and lakes. During this time period, Sugar Island, which is one of the twelve islands commonly considered to comprise Grosse Ile, featured an amusement park, dance pavilion, and bathing beach. Paddle steamers regularly carried people from Detroit and other points along the Michigan side of the Detroit River to Sugar Island.

During this era and into the early 20th century, a number of wealthy residents from Detroit and other nearby towns built summer homes along the shoreline (mainly on the southern end) of Grosse Ile in order to enjoy views of the Detroit River or Lake Erie. The interior section of the island was sparsely populated, as most of the land was undeveloped woodlands or part of farms. The residential population of Grosse Ile totaled 802 at the 1920 U.S. Census. The majority of houses were located around the perimeter of the island and main roads crossed the community chiefly in either a north–south or east–west direction.

In 1894, the federal government funded and constructed a series of channel range lights to assist ships to avoid shallow areas in the Detroit River and its shoreline. The northernmost of the channel range lights was the Grosse Ile Light, which is now the only lighthouse remaining on the island. The original 1894 Grosse Ile lighthouse resembled a water tower on stilts, as it was constructed on wooden pilings along with a walkway to shore.

It was rebuilt in 1906 and designed as the classic white structure that has become one of the iconic landmarks on the island. The lighthouse is considered a symbol of Grosse Ile; its image is used on the masthead of the Ile Camera community newspaper and many other places. The lighthouse's beacon was turned off in the 1940s, and the structure is no longer an important navigation aid for lake freighters. Small boaters still refer to the lighthouse in their navigation of the area.

In 1965, the Grosse Ile Township purchased the lighthouse from the U.S. Department of the Interior for $350, with funds provided by the Grosse Ile Historical Society (GIHS). The GIHS was given the responsibility to preserve and maintain the lighthouse. The GIHS annually holds a tour of the lighthouse during a weekend each fall, which is the only time of the year that it is open to the public.

Island resident Cameron Waterman invented the outboard motor and successfully tested his invention during February 1905 in the ice-filled Detroit River off the shore of Grosse Ile. He established the Waterman Marine Motor Company in Detroit. The company eventually manufactured and sold up to 1,000 outboard motors per year until Waterman sold the business in 1917. During the fall of 2005, the GIHS celebrated the 100th anniversary of Waterman's invention by hosting a public exhibition featuring fully restored Waterman outboard motors. These are highly collectible and very rare.

During the Prohibition era, Grosse Ile became a crossing point for bootleggers illegally smuggling alcoholic beverages from Canada. They typically arrived at the island via small speed boats. During the winter months, some daring smugglers drove cars across the frozen river.

Aviation and military

During the 1920s and 1930s, a small airport on the southern end of Grosse Ile was the location of historic early aviation activities. The Curtiss-Wright Flying Service operated a flying school at the airport. The Aircraft Development Corporation built the world's first all-metal airship, the ZMC-2, for the Navy in a large hangar. Amelia Earhart is rumored to have stopped at the airfield on occasion.

Grosse Ile was the home of a U.S. Navy base for forty years. The U.S. Naval Air Station Grosse Ile opened in 1929 after three years of construction of seaplane and dirigible facilities. During World War II, the naval base developed into an important center for military flight training. The base was expanded considerably to accommodate large numbers of American and British fliers who trained on the island. As a young man during WWII, George H. W. Bush was stationed at the base for training during 1945 for about two months. He later became a politician and President of the United States.
