WASHINGTON (AFP).- The elevator brings visitors up out of the dull, beige maze of the US State Department's bureaucratic warren and back in time to a hall lined with period décor recalling the era of the American Revolution.

The 18th century backdrop is artificial -- plaster and resin overlaying the modern office structure -- but the diplomatic reception rooms house a unique collection of 5,000 historic artefacts. 

When the state rooms were first opened in 1961, the institutional office furniture made them look, in the words of their late former curator Clement E. Conger, "like a 1950s motel."

"It was a disaster by any standards for elegant entertaining and international diplomacy," Conger wrote, describing how he undertook to transform the space into a tribute to American craftsmanship and cultural heritage.

Conger's team brought together a collection of objects and furnishings dating from early American history, from 1740 under the British Empire, through the 1776 Revolution to 1830. 

Some belonged to supporters of the fledgling republic, including some to the Founding Fathers of the United States, others to loyalists to the Crown. Some have diplomatic significance, others are simply a tribute to the skilled artisans of the era. 

Thus, in pride of place, visitors can find the desk on which was signed the 1783 Treaty of Paris that brought to an end the Revolutionary War in which the United States won independence from Britain.

Nearby, sits an unfinished sketch for a painting which ought to have commemorated this moment: The five US negotiators, including Benjamin Franklin, are already finished, but the British representative refused to pose for the artist.

Marcee Craighill, current curator of the Diplomatic Reception Rooms, beams with pride as she explains how this work will soon grace the halls of a French royal palace as part of a temporary exhibition: "Versailles and American Independence."

Today, the reception area comprises 42 rooms covering 28,000 square feet (2,600 square meters) on the seventh and eighth floors of the State Department's Harry S Truman Building in downtown Washington's Foggy Bottom district.

The refurbishment was paid for by private donations in cash and kind, Craighill says, and today the art and artefacts have an estimated value of $125 million. 

But that is without counting the architectural decor, which allows today's diplomats and statesmen to discuss world affairs against a backdrop of moldings and ceilings based on famous stately homes.

Part of the area forms a reproduction of Thomas Jefferson's mansion in Monticello, Virginia, just south of the US capital, and others use marble and hardwood floorings recovered from historic buildings.

The grandest chamber, the Benjamin Franklin State Dining Room, has a 21 foot (6.4 meter) ceiling and a 98-foot floor rug that weighs 4,000 pounds, under a table that can sit 375 dignitaries.

"We wanted guests to have the impression of entering an 18th century American house," Craighill said.

The art of statecraft
Every year in August the state rooms are closed for cleaning -- part of their $300,000 annual upkeep -- but for the rest of the year they play host to the daily rituals of world diplomacy.

International summits, bilateral negotiations, press photo opportunities, working dinners with foreign dignitaries -- hundreds of events take place every year. 

"The artwork plays a role whenever possible in the art of diplomacy, in the dialogue with foreign leaders," Craighill told AFP on a recent tour.

For example, in March paintings representing the Niagara Falls were moved to pride of place during a visit by Canadian Prime Minister Justin Trudeau  to celebrate "visual highlights of our shared border."

The collection is also testament to the long-standing commercial ties of a rising world leader. One porcelain dinner set shows the founding fathers with Asiatic features, having been painted by Chinese craftsman who had never seen a European face. 

The rooms, hidden away on top of the otherwise fairly unremarkable office block, are not a huge draw on Washington's well-beaten tourist trail. Only 20,000 visitors per year join guided visits.

But diplomatic events and educational programs bring another 100,000 people to the rooms each year, and the venue remains popular enough to support its upkeep through private donations -- as US law forbids public funding for such luxury.
