US novelist Kurt Vonnegut, a prisoner of war in Dresden during World War II, has a scene in Slaughterhouse-Five where time-travelling hero Billy Pilgrim sees the city’s firebombing in reverse, with phosphorous bombs being sucked back into warplanes.

Visitors today to the German city that proudly, if a bit cheekily, calls itself ‘Florence on the Elbe’, in a nod to its Italianate architecture, could almost think the scene was prescient of Dresden’s resurrection since then.

Imprisoned at a slaughterhouse that inspired the novel’s title, Vonnegut lived through the infamous bombing raid on February 13, 1945, which destroyed the old part of the city three months before the war in Europe ended. It killed, according to widely varying estimates, 35,000 to 100,000 people, or more.

Emerging from the relative safety of the slaughterhouse, Vonnegut wrote that the destroyed city looked like a moonscape.

Today the moonscape can be seen only in photographs, although there have been plenty of them over this month as the city, and the world, remembered the 70th anniversary since the Allies attacked.

Sited on land that slopes up gently from the scenic Elbe in the historic kingdom of Saxony, Dresden, formerly part of communist East Germany, is one of the beneficiaries of German unification.

Its booming semiconductor, pharmaceutical and manufacturing industries, including a glass-fronted factory that produces Volkswagen’s luxury Phaeton model, and is a tourist attraction in its own right, mean the city is flush with cash to support a thriving restaurant, boutique and cultural and arts scene.

One of Germany’s most prestigious opera houses, the Semperoper, which saw the premieres of nine of Richard Strauss’s operas and three of Richard Wagner's, dominates a vast square.

Nearby, the Gemaldegalerie Alte Meister (Old Masters Picture Gallery) has a spectacular collection including works by Rubens, Durer, Rembrandt and Canaletto, plus touchstones of art such as Raphael’s Sistine Madonna and Vermeer’s Girl Reading a Letter at an Open Window.

Dresden is also the site of a modern miracle in the reconstruction of its historic old town, especially the rebuilding of the 18th century Frauenkirche (Church of Our Lady).

The heart and soul of the old city collapsed into rubble two days after the bombing raid due to the intense heat generated by the firestorm.

While the communist authorities who ran East Germany until 1989 spent money to rebuild the destroyed Semperoper, they would not pay for the church.

Townspeople cleared the site and stored the remaining original stones nearby, waiting for their time to come, which it did when communism collapsed and the Berlin Wall fell.

With donations from throughout the world, including a substantial sum from a trust in Coventry, England, scene of another devastating church bombing in World War II, the Frauenkirche was rebuilt from the rubble.

Since it reopened in 2005, it has become one of the top five tourist attractions in Germany, partly for its meticulously restored, pale white baroque interior, partly because it has a reputation for being ‘the biggest puzzle in the world’.

Dotted throughout the church, inside and out, are the dark original stones, reinserted in their former positions as a result of painstaking research and computer-imaging technology. The result is striking and extraordinary: a mostly light-coloured structure flecked with dark that provides a stark visual reminder of the cruelty and destruction of war.

Dresden has another side, largely courtesy of the Wettin dynasty which ruled Saxony for more than 800 years and began building palaces in what had been a small fishing village on the banks of the Elbe.

One of the more fantastic architectural legacies of Wettin rule is the sprawling Zwinger complex, essentially a folly inspired by Versailles and consisting of ornate baroque buildings that were never really intended as living quarters.

Instead, the Zwinger was the setting for one of the longest and most lavish parties of the 18th century.

Friedrich August, the only known legal son of Augustus II, whose nickname was Augustus the Strong and who was fabled to have had 500 mistresses and 365 children, married a Habsburg princess in 1719.

‘Half of Europe’ was invited to the party, which lasted four weeks and cost a then princely sum of four million thalers.

Like other royal buildings, the Zwinger suffered extensive damage in the war, but was rebuilt in its original style in the 1950s and 1960s. It houses a magnificent porcelain collection and also, in a wing designed in a later style, the Old Masters Picture Gallery.

A clock at one end of the Zwinger’s open courtyard features Meissen-porcelain bells that chime the hours.

Porcelain, which came to Europe from China, was considered as ‘white gold’ and Augustus the Strong was anxious to develop his own source.

When an alchemist came up with a process to make it, the Saxon ruler promoted the creation of workshops at Meissen, a small town northwest of Dresden, to manufacture porcelain which is still made there today.

Communist authorities would not pay to rebuild the Frauenkirche. Townspeople kept the remaining original stones and waited for their time to come

A Procession of the Princes mural that stretches 102 metres along the wall of the royal stables was painted in the late 1800s to celebrate the 800th anniversary of the dynasty.

Between 1904 and 1907, to preserve it, the painting was replaced with 23,000 Meissen porcelain tiles depicting the same scene, making it the largest Meissen porcelain artwork in the world.

Volkswagen’s ‘transparent factory’ allows visitors to watch a car being assembled, with one of the highlights being the moment when the finished vehicle is twirled up into a glass-enclosed tower-like holding area. (www.glaesernemanufaktur.de/en, tours must be booked by telephone beforehand).

But almost nothing compares to Dresden’s Deutsches Hygiene-Museum (www.dhmd.de), a museum of public health and sciences that explores pretty much every aspect of human life, from birth to death, containing exhibits that leave nothing to the imagination.

A visitor knows this is going to be an unusual experience from the first room. It features a black metal X-ray machine from the 1920s that is about the size of small car and features large dials and a tubular glass ray-emitting tube that would look right at home in Dr Frankenstein’s lab.

A bit further on are foetuses at several stages of development preserved in glass containers, exhibits of the instruments needed to deliver a baby and display cases showing how a child is conceived, and how it develops in the womb.

There are bus sightseeing tours of the entire city and cruises of the Elbe River, from April until the fall.

One thing to bear in mind with German cooking, if you are a vegetarian, is that sometimes the vegetable dishes contain meat.

That is the case with the sauerkraut and fried potatoes served at the Augustiner An der Frauenkirche, near the famous church.

The Augustiner in other respects is the ideal place to fill up on hearty German cooking, from a plate of roasted Nuremberg-style sausages to a grilled pork knuckle to roast duck goulash.

Side dishes include cucumber salad and tomato salad, while the menu advertises at least one ‘big mixed salad’ with no hint of meat, though it might be a good idea to ask.

The draft beer is superb and it would be hard to spend more than €25 per person, easy to spend far less.

Rauschenbach Deli, across the main boulevard from the old city, is among a half dozen restaurants on Weisse Gasse offering everything from tapas to Vietnamese food.

Pork knuckle is on the menu, but Rauschenbach also has salmon fillet in a leak and cream sauce and on a recent visit served a perfectly cooked halibut portion in a similar sauce.

There are pasta dishes that do not contain meat or fish, and with a glass of wine or stein of beer, plus a starter, the tab is about €30 per person.

Alte Meister Cafe & Restaurant, a step away from the Old Masters gallery and the Semperoper, is installed in the elegant surroundings of the former mansion of the architect who rebuilt the Zwinger.

Specialities include pork belly with herbs or veal in a parsnip and mustard crust with gravy, green peppers, radishes and layered potatoes. Allow €35 to €40 per person.

The waiters and waitresses in the Sophienkeller, Taschenberg 3, near the posh Kempinski Hotel, wear local costume and the food has a Saxon theme, including a Saxon potato soup with sausage, grill-roasted suckling pig and Saxon Quarkkaulchen, which is described as a speciality made from potato and curd, fried and rolled in sugar with apple sauce.

You won't go away hungry and the tab should be about €30 per person.

There is a friendly and lively row of cafes and bars, many of them open late, behind the Frauenkirche on Munzgasse, running down to the riverfront.

But for a younger scene, the place to go is across the river to the ‘new city’, where most of the clubs, cafes, cinemas and nightlife are located.

A nice way to ease into the scene is to start at Cafe Scheune at Alaunstrasse 36-40 (www.scheune.org). This is a multi-purpose venue featuring a laid-back bar and cafe with a Pakistani-Indian restaurant that also serves a wicked Sunday brunch.

Upstairs is a theatre which, depending on the day, offers music, plays, poetry slams, dance parties, book readings and more.

It would help to speak German, but command of the language is not necessary to dance or enjoy the music.

The area includes more cafes and bars, clothes shops and a more eclectic range of restaurants than the old town.
