The French warship “La Fayette” and its crew are in New Orleans this week to celebrate the 250th anniversary of the birth of the Marquis de La Fayette, a French aristocrat who fought in America’s War of Independence.

French sailors sounded a 21-gun salute as the frigate arrived at the Port of New Orleans Tuesday. The U.S. Navy responded with a 21-gun salute of its own — a long-held naval greeting dating back to the 1700s for a ship making its first port of entry in a new country.

“This visit is important to the history of friendship between France and Louisiana and the history of friendship between France and the United States,” said Pierre Lebovics, the French consul general in Louisiana, who was standing dockside.

The frigate will be docked on the banks of the Mississippi River near the French Quarter through Friday. On Saturday, it departs New Orleans for Tampa, Fla., then Norfolk, Va., and Savannah, Ga.

The ship’s officers, led by Capt. Jean-Philippe Rolland will participate in a wreath-laying ceremony Wednesday in the city’s devastated Lower 9th Ward to memorialize the victims of Hurricane Katrina.

Also Wednesday, French naval officials will bestow the “Legion of Honor” — a prestigious French military and civilian honor — on five American World War II veterans in a ceremony aboard the ship.

Born Sept. 6, 1757, the Marquis de La Fayette ignored France’s early neutrality during the American Revolution and traveled to the United States, where he fought alongside the Americans. He gained the rank of major general and served under George Washington.

He remained active in French and European politics until his death on May 20, 1834.

On Thursday, French naval officials will visit the Louisiana city of Lafayette, which is about 130 miles west of New Orleans.

The “La Fayette” combat ship was constructed in a naval shipyard in Lorient, France, beginning in the late 1980s. It was launched in 1992 and commissioned in the mid-1990s.

The public will be allowed to tour the ship on Thursday and Friday, between 1:30 p.m. and 6 p.m., said Lt. Brian Bradshaw, a port operations officer for naval vessels in New Orleans. Visitors will need to have photo identification, he said.

New Orleans was founded by the French in 1718 and France has centuries-old cultural and economic ties to Louisiana. After Hurricane Katrina hit in 2005, France hosted Louisiana musicians, giving them rent-free apartments and helping them book performances for months when they had few places to play back home.

The French government, French companies and private donors of French heritage also have funded preservation of historic architecture in New Orleans and schools that offer French-language immersion programs.
