Rasnov, Romania ? Mozart’s “Requiem” floats over the walls of a 14th-century citadel and wafts down the snowy slopes that tower over this Transylvanian town.

Little wonder that the producers of “Cold Mountain” chose this enchanting location to film the biggest Hollywood movie ever made in Romania. Its medieval charm long has lured thousands of tourists — and the scenery in the film is bound to entice many more.

Directed by Anthony Minghella and starring Nicole Kidman, Jude Law and Renee Zellweger, “Cold Mountain” was shot in 2002 in the mountains and forests of this magical corner of southeastern Transylvania and released at Christmas.

Based on the novel by Charles Frazier, it tells the wrenching odyssey of a wounded Confederate soldier who returns to his North Carolina home. Though the story is set in Virginia and North Carolina, nearly all of the movie was filmed in Romania because of its landscape and low costs.

Minghella found the unspoiled beech and birch forests and mountains — home to bears, deer and wolves — and the rural farmlands the closest thing to the North Carolina of the Civil War.

Medieval charm

Yet there’s more to the region than spectacular scenery.

Tourists are drawn by the Dracula legend and the medieval charm haunting this land that endured centuries of invasion.

In the area there are 15 citadels and fortresses, which were built by peasants to keep out marauding armies of Turks and Tartars and cruel local medieval lords. Many have been preserved or renovated, and breathe an air of timelessness in a land at once in the 14th and 21st centuries.

The most famous is Bran Castle, a Gothic fortress perched on a rock. It needs only a couple of bats in the late afternoon to make it the perfect setting for a horror film; and indeed, the castle has appeared in numerous Dracula movies.

Getting there: Trains from the capital, Bucharest, to Brasov cost up to $9. The trip takes 2 1/2 to four hours depending on the train. After reaching Brasov, there are regular bus lines that run every half-hour and take 20 minutes to get to Rasnov. They cost 30 cents. Rental cars and taxis also are available.Lodging: Inns and guest houses, called “pensiune” in Romanian, are plentiful. Depending on their facilities, they cost from $12 up to $19 per night per person. There are good hotels in the ski resorts of Poiana Brasov and Predeal. A three-star hotel in Predeal costs $125 a night. The Count Kalnoky Castle in the village of Miclosoara is popular with foreigners and costs $57 a night. In the summer, there are camping facilities at reasonable prices. What to do: Visit one of the 15 medieval fortresses in the region, which is known as Tara Barsei. The best known is Bran Castle, also called Dracula’s Castle. The 13th-century citadel in the village of Cristian is well-known for its bells, while the Prejmer citadel is the area’s largest. Winter offers skiing at Poina Brasov or Predeal. Hiking is also popular in the Carpathian Mountains, although not recommended in winter, when temperatures plunge well below freezing. The city of Brasov is worth a visit; so is the medieval city of Sighisoara, a little farther afield (three hours by car).Information: Tourism office in Bucharest, phone (011-40-21) 314-9957; Romanian tourism office in New York, phone (212) 545-8484; Web sites www.romaniantourism.com or www.transylvaniancastle.com.

Romania’s most infamous prince, Vlad the Impaler — admired for defending this corner of Transylvania from Turkish invasions by cruelly impaling Turks and thieves on wooden stakes — was the real-life inspiration for “Dracula,” author Bram Stoker’s 1897 novel.

Tourism has developed here since communism ended in 1989, allowing private enterprise to flourish.

Comfortable and clean inns are dotted along the roads of villages and towns for those who dare to drive the area’s hairpin mountain turns and precipitous drop-offs.

Much of the local food is heavy, suitable for a winter mountain climate, and the ingredients are often organically grown.

Hard-core Dracula fans will find the Wolves’ Inn, tucked just a few fields away from where filmmakers built the “Cold Mountain.” In Rasnov, there’s also the Count’s Home hotel.

At the gates of Bran Castle, vendors offer Dracula sweaters hand-knit from the thick wool yield of local sheep, and offer Vampire wine — red, of course. It’s an easy day trip from the popular ski slopes at nearby Poiana Brasov.

Visitors welcome

The picturesque town of Rasnov, 100 miles northwest of Bucharest, received $600,000 for serving as the backdrop to “Cold Mountain.” But Mayor George Soiu is disappointed that the filmmakers didn’t leave the set behind — he had hoped to turn it into a rural inn.

The site where the movie’s main scenes were filmed is just a short drive across snowy fields.

The mountain is called Cheita, or the Little Key, and looks pretty much like dozens of other mountains in the area. There are riding and bungee jumping facilities in the nearby fields.

As many as 200 people visit daily in the summer months, and winters draw a couple of dozen a day. Among the more unusual Transylvania tourist attractions at the citadel is a glass panel in the floor through which visitors can peer at a human skeleton lying in an open grave.

“Foreigners come here for Dracula,” said Catalin Coman, a 20-year-old Romanian student enjoying a pizza with his girlfriend at Bran before returning to his studies in Germany.

“We must take advantage of this legend,” he said. “We have a beautiful country and it’s shame not to make money from tourism.”
