Father Marquette National Memorial pays tribute to the life and work of Jacques Marquette, French priest and explorer. The memorial is located in Straits State Park near St. Ignace in the modern-day U.S. state of Michigan, where he founded a Jesuit mission in 1671 and was buried in 1678. The associated Father Marquette Museum building was destroyed in a fire on March 9, 2000.

St. Ignace ( IHG-nəss) is a city in the U.S. state of Michigan and the county seat of Mackinac County. The city had a population of 2,306 at the 2020 census. St. Ignace Township is located just to the north of the city, but the two are administered autonomously. St. Ignace is located along Lake Huron in the Upper Peninsula on the northern side of the Straits of Mackinac. The city serves as a gateway to the state's Upper Peninsula for travelers coming from the Lower Peninsula, as the city is at the north end of the Mackinac Bridge, opposite Mackinaw City. It has one of two ports which provide ferry service to nearby Mackinac Island. St. Ignace's history dates back to 1671 when French Jesuit priests founded the St. Ignace Mission, which makes it one of the oldest European settlements in the state after Sault Ste. Marie. The area was previously inhabited by the Wyandot people, as well as the Ojibwe and Ottawa tribes of Native Americans. St. Ignace soon became the center of fur trading with the French. It was incorporated as a village in 1882 and a city in 1883. The Mackinac Bands of Chippewa and Ottawa Indians is headquartered at St. Ignace, and the city continues to have a high population of Native Americans.

The John Chambers House is an originally residential building located at 90 North State Street in St. Ignace, Michigan. The house is currently operated as the Colonial House Inn. It was listed on the National Register of Historic Places in 1982.

Fort de Buade was a French fort in the present U.S. state of Michigan's Upper Peninsula across the Straits of Mackinac from the northern tip of lower Michigan's "mitten". It was garrisoned between 1683 and 1701. The city of St. Ignace developed at the site, which also had the historic St. Ignace Mission founded by Jesuits. The fort was named after New France's governor at the time, Louis de Buade de Frontenac.

This is a list of all lighthouses in the U.S. state of Michigan as identified by the United States Coast Guard. Michigan is home to lights on four of the Great Lakes, Lake St. Clair and connecting waterways. The first lighthouse in the state, Fort Gratiot Light, was erected in 1825. It is still active. The Michigan.gov website does not have a Map of Michigan Lighthouses in PDF format anymore. If not otherwise noted, focal height and coordinates are taken from the United States Coast Guard Light List, while location and dates of activation, automation, and deactivation are taken from the United States Coast Guard Historical information site for lighthouses.

East Moran Bay is a small, historic harbor in the Straits of Mackinac adjacent to the city of St. Ignace in the U.S. state of Michigan. The harbor is used as a commercial port for Star Line Ferry and Shepler's Ferry ferry boats from St. Ignace to Mackinac Island, a tourist center of the Straits of Mackinac. The bay and its harbor are guarded by the Wawatam Lighthouse.The bay is a traditional place for fishing, and several St. Ignace archaeological sites associated with Native American history are located adjacent to the bay. In historical times, the bay was used as a harbor by the Mackinac Transportation Company, operator of train ferries; the Vacationland and her sister vessels, which crossed the Straits carrying motor vehicles; and the Arnold Transit Company ferry boat line to Mackinac Island. State historical markers describe the history of the harbor. A bottomland survey of East Moran Bay was performed by the Michigan Underwater Preserve Council and its volunteer sport divers in the early 1900s and published by the United States Government Printing Office in 1992. The city of St. Ignace has built and maintains an East Moran Bay waterfront path, the Huron Boardwalk, marked with signs and artifacts, to interpret and celebrate the bay and its heritage. The artifacts include the remains of a Mackinaw boat built about 1899.

The Mackinac Bridge Walk is an annual event held every Labor Day since 1958 in Michigan in which people may walk the length of the Mackinac Bridge. Walkers are traditionally led across by the governor of Michigan. In an average year, 40,000 to 65,000 people participate in the five-mile walk. This is nearly the combined population of the three counties connected by the bridge. The Labor Day bridge walk is the sole exception to the rule prohibiting pedestrians on the bridge.

Green Island is an island in Mackinac County, Michigan. The island is located in the Straits of Mackinac in Lake Michigan. Green Island is approximately 16.46 acres (6.66 ha) in size. The island is uninhabited and covered in thicket with a few trees scattered throughout. It is .25 miles (0.40 km) south of Point La Barbe on the Upper Peninsula shore. Green Island also lies 1 mile (1.6 km) west of the Mackinac Bridge. It is privately owned.

The Mackinac Bridge ( MAK-ə-naw; also referred to as the Mighty Mac or Big Mac) is a suspension bridge that connects the Upper and Lower peninsulas of the U.S. state of Michigan. It spans the Straits of Mackinac, a body of water connecting Lake Michigan and Lake Huron, two of the Great Lakes. Opened in 1957, the 26,372-foot-long (4.995 mi; 8.038 km) bridge is the world's 27th-longest main span and is the longest suspension bridge between anchorages in the Western Hemisphere. The Mackinac Bridge is part of Interstate 75 (I-75) and the Lake Michigan and Huron components of the Great Lakes Circle Tour across the straits; it is also a segment of the U.S. North Country National Scenic Trail. The bridge connects the city of St. Ignace to the north with the village of Mackinaw City to the south. Envisioned since the 1880s, the bridge was designed by the engineer David B. Steinman and completed in 1957 only after many decades of struggles to begin construction. The bridge has since become an iconic symbol of the state of Michigan.

The Straits of Mackinac Shipwreck Preserve is a 148-square-mile (380 km2) state preserve in and around the Straits of Mackinac. The preserve is divided in two by the Mackinac Bridge. The waters of the preserve include the waters offshore from Mackinaw City and St. Ignace, as well as all or part of the shorelines of Bois Blanc Island, Mackinac Island, Round Island, and St. Helena Island. The preserve contains at least eleven identified diveable wrecks, with more just outside the official boundaries. There are also a number of shallow sites suitable for snorkeling and kayak visits. Frequent fog and congested shipping added to the count of shipwrecks in the Straits area. Half a dozen lighthouses in and around the preserve testify to the dangers that existed prior to the invention of radar in the 1940s. However, tragedies have continued. One modern wreck within the boundaries of the preserve is Cedarville, a lake freighter transporting limestone that sank in 1965 after a collision. Divers also visit underwater formations of Mackinac breccia near Mackinac Island; one such formation, the "Rock Maze", is offshore from Arch Rock. Further east off Arch Rock, a drowned, 100-foot (30 m)-high waterfall formation, Mackinac Falls, was discovered in August 2007.
