Salzburg's Altstadt is a UNESCO World Heritage Site, its Baroque architecture packed into a compact area beneath the fortress. Along the Getreidegasse, where Mozart was born, wrought-iron guild signs hang above shop fronts - traditions preserved now for commercial rather than functional reasons. Step off the narrow streets and civic squares open up: the Residenzplatz, the Domplatz, the Mozartplatz, each one shaped by the spatial demands of Baroque urbanism.

Churches crowd the old town, their interiors a catalog of Baroque extravagance. The Cathedral rises with three domes. The Collegiate Church displays a Bernini-influenced facade. Inside the Franciscan Church, a nave predating the Baroque additions reminds visitors how many centuries of architecture overlap here. All remain active places of worship, their religious purpose continuing alongside the tourism revenue that funds their preservation. Hours will cover the old town's ground, but days reward deeper exploration.

Hohensalzburg Fortress crowns the Festungsberg, its white walls visible from every corner of the city below. Construction began in 1077. Over five centuries of expansion, it grew into the largest fully preserved fortress in Central Europe. Prince-archbishops intended it as a refuge, not a residence; the funicular carrying today's visitors began as a supply line for the garrison.

Climb up, and the reward is immediate - sweeping views over the old town and southward toward the Alps. Inside, state rooms recall the archbishops who once entertained here, while a torture chamber speaks to how they maintained discipline. Museum collections trace the centuries of history these walls witnessed. Concerts now fill the rooms, extending the cultural tradition Salzburg claims as birthright. From nearly anywhere in the city, look up: the fortress is always there, the reference point by which all navigation orients itself.

On January 27, 1756, Wolfgang Amadeus Mozart was born in a building on the Getreidegasse - now both museum and pilgrimage site. His relationship with Salzburg was never simple. He worked here for the prince-archbishop, chafed under provincial constraints, then departed for Vienna, where he achieved greatness and died in poverty. Salzburg claims him with an intensity his departure might not warrant. The city that couldn't hold him now won't let him go.

Mozart pervades modern Salzburg. Every shop sells Mozartkugeln chocolate balls. Every hotel promotes Mozart concerts. Statues, plaques, and his name fill public spaces. For serious music, the Mozart Week festival arrives each January; in summer, the Salzburg Festival draws opera lovers willing to pay premium prices. Mozart is the city's brand, and the brand building started long before modern marketing was invented.

From April to May 1964, Salzburg and its surroundings served as the filming location for The Sound of Music. The fictional von Trapp family's haunts became real-world pilgrimage sites. Daily tour buses visit Leopoldskron Palace, which stood in as the von Trapp house exterior, the gazebo where Liesl and Rolf danced, and Mondsee Abbey, setting for the wedding scene. Passengers sing along to the soundtrack as they go.

Here is the curious thing: this tourism is almost entirely American. The film never achieved the same success in Europe, and most Austrians find the whole phenomenon puzzling. Tours cater to American nostalgia. Shows perform the songs. Merchandise celebrates a Hollywood version of Austria that Austrians barely recognize - cultural export reimported as tourism. Are the hills around Salzburg genuinely beautiful? Without question. Whether they are alive with music depends entirely on the observer.

Hugo von Hofmannsthal, Richard Strauss, and Max Reinhardt founded the Salzburg Festival in 1920. It has since become one of the world's premier music and drama festivals, commanding ticket prices that reflect decades of earned prestige. Performances unfold across the city: in the Grosses Festspielhaus carved into the cliff face, in the Felsenreitschule housed within a former riding school, and in various theaters and churches hosting smaller productions.

Each summer, the festival transforms Salzburg. Its visitors differ markedly from the day-trippers who arrive year-round. Evening dress is expected. At intermission, audience members gather and quietly assess one another. Reviews published the next morning can determine reputations. This is a cultural world tourism has not diluted. The festival embodies what Salzburg aspires to be - the high culture invoked by Mozart's name, thriving in a city where tourism elsewhere risks compromise.
