MADELINE ISLAND, Wis. >> England’s ancient Arthurian legend is alive and well in northern Wisconsin, albeit with a slight twist.

Those who read “Le Morte d’Arthur” by 16th-century author Sir Thomas Malory will remember it was prophesied that King Arthur, armed with his mighty sword Excalibur, would return from the isle of Avalon at the hour of Britain’s greatest need.

The Isle of Avalon, a mythical spot in the southwest of England, is a long way from the Apostle Islands off the shore of Lake Superior. Every year, thousands of visitors flock to the 22 islands that make up Apostle Islands National Lakeshore to admire the unusual formations of craggy rocks sculpted by nature into a labyrinth of caves, delicate arches and vaulted chambers.

But it’s a safe bet that many of them are unfamiliar with the Ojibwe legend that tribal elders buried sacred scrolls somewhere inside the network of caves that would elude discovery by all but a little boy — who would presumably return one day to guide his people.

I learned the legend from Ojibwe tribal member Mike Wiggins, site director of the Madeline Island Museum, a fascinating repository of artifacts celebrating all the cultures (Ojibwe, French, English and American) who have called this largest of the Apostle Islands home.

An ambitious two-year museum exhibition, “Passages: Ojibwe Migration to the Place Where the Food Grows on the Water,” chronicles the tribe’s journey through the eyes of their ancestors.

After getting a thorough introduction to the region by Wiggins, I went by boat to see the chiseled formations of Devil’s Island with their honeycomb of caves but, alas, found nothing to indicate the scrolls’ whereabouts.

Madeline Island Museum is only one of the 11 sites managed by the Wisconsin Historical Society.

These sites range from the first to be established (1954), Villa Louis, a fur-trader’s mansion in Prairie du Chien, to the newest addition, Black Point Estate and Gardens in Lake Geneva, a Chicago beer baron’s mansion brought under the Historical Society umbrella in 2005.

I made it to Black Point, and the adage “getting there is half the fun” was never more true.

The only way for most people to get there is by boat (they have alternate arrangements for disabled guests; you’ll soon learn why), and the 90-minute round-trip cruise took me past the palatial summer homes of early Chicago titans of industry.

When he built Black Point in 1888, Conrad Seipp, a German immigrant who founded his own brewing company, wanted a private retreat. He discouraged “drop-ins” by erecting it atop a forested hill, where determined visitors must make their way from the boat dock up a winding staircase of 120 steps.

It’s worth the huffing and puffing. The 8,000-square-foot mansion is a fine example of Queen Anne/Victorian-style architecture. The interior is equally impressive with features such as stained-glass windows and an exquisite blue tiled fireplace in the sitting room.

Old World Wisconsin

The third stop on my historical tour was Old World Wisconsin, a collection of structures moved from their original locations throughout the state to the 600-acre site in the community of Eagle.

Adjacent to the Kettle Moraine State Forest, Old World Wisconsin was begun as part of America’s Bicentennial Project in 1976.

You’ll need comfortable shoes — touring more than 60 structures depicting 19th-century rural life in the nation’s heartland requires a lot of walking.

Costumed interpreters invite visitors to shake hands with history in buildings such as Four Mile Inn, built in 1853 as a stagecoach stop and tavern; the 1876 general store that once sold everything from bolts of cloth to gunpowder (today’s visitors will have to settle for gunpowder tea); and the one-room 1900 Raspberry Schoolhouse, which, ironically was built in 1896 and could be mistaken for a “Little House on the Prairie” set.

You can learn how to make coffeecake from a recipe dating to 1883; watch a weaver at her loom at the Pomeranian Immigrant Farm; and learn the heritage of Pomeranian, Hessian, German, Scandinavian and African-­American settlers in their respective villages.

You need an entire day to thoroughly explore Wisconsin’s version of Colonial Williamsburg.

History doesn’t stop

Wisconsin is serious about its history as it plans for the opening of the state-of-the-art History Center in the capital city of Madison in 2027. But who says history has to be just events from the distant past?

If you book a stay at the Four-Star Grand Geneva Resort & Spa, you’ll find two championship courses, a full-service spa and elegant dining in both the Geneva Chophouse and Ristorante Brissago.

What you won’t find is much evidence — except for the hidden bunny logo across from the Chophouse — that the Grand Geneva now occupies what was the first Playboy Club Resort in the United States.

If you’re looking for history with a hot meal, you’ll do no better than the Duck Inn Supper Club outside Lake Geneva in the town of Delavan.

Originally built in 1920 during Prohibition, guests had to covertly “duck in” and “speak easy” to avoid detection from government officials. A trap door (still in existence) led to a basement where gambling and drinking went on, and rumor has it that Al Capone, who owned a property on Lake Geneva, was a frequent visitor.

Go ahead and order a Brandy Old-Fashioned, Wisconsin’s official state cocktail. No one will prohibit you anymore.
