15 Best Sights in Vienna Woods, Lake Neusiedler, and the Danube River, Austria

With roots dating back more than a millennium—it was first mentioned in 907 for its role in a battle between Bavarians and Hungarians—Bratislava Castle was significantly rebuilt in the Renaissance style in the mid-16th century. It's this enormous, rectangular form with four stocky towers that you can see today (though it incorporates architectural features from throughout its history, and the dazzling white paint job is distinctly 20th century). Walk up the (steep) castle hill and pass through one of the four entrance gates (probably Viedenská brána or Leopoldova brána) for incredible views of the town and the Danube below. The grounds are free to enter, so you can soak up the vistas as long as you like; make sure you visit the beautiful Baroková záhrada (Baroque Garden) while you're at it. You only need to pay if you want to head inside, either for the SNM-Historical Museum, which is a little sparse but does include access to the Crown Tower via a narrow passageway, or any of the regularly changing temporary exhibits.

The enormous golden crown and cushion on top of this beautiful Gothic cathedral reveals that this was once a coronation church. In fact, it was the coronation church for Hungarian (and later Austrian) monarchs for more than 250 years; 19 different royals were crowned here between 1563 and 1830, including Empress Maria Theresa. The church was also one of the city's lines of defense, which explains the chunky walls, the arrow-slit windows, and the exceptionally tall (lookout) tower. Luckily, the interior is more delicate and decorative, with dramatic rib vaults, colorful stained glass windows, and a grand altar showing St. Martin in a traditional Hungarian hussar dress. Next to the cathedral lie the remains of the Neologická Synagóga (Neological Synagogue), demolished by the communist government in the 1970s, and overlooked by the glorious facade of the Lekáreň u Salvátora (Pharmacy Salvator).

This symbol of Sopron’s endurance—and entranceway to the Inner Town—is 200 feet high, with foundations dating to the days of the Árpád dynasty (9th–13th centuries) and perhaps back to the Romans. The tower is remarkable for its uniquely harmonious blend of architectural styles: it has a Romanesque base rising to a circular balcony of Renaissance loggias topped by an octagonal clock tower that is itself capped by a brass Baroque onion dome and belfry. The upper portions were rebuilt after most of the earlier Fire Tower was, ironically, destroyed by the Great Fire of 1676, started by students roasting chestnuts in a high wind (today a double-headed eagle weathervane helps to predict wind direction; it's said that if the eagles face north and south it's going to rain). On the inside of the gate, you'll find a depiction of "Hungaria" receiving the loyalty of Sopron's kneeling citizens. Climb the 200-step spiral staircase to the top of the tower for lovely views of the town and surrounding countryside. It's from here that tower watchmen warned of approaching enemies and tolled the alarm for fire or the death of a prominent citizen. And occasionally, musicians would serenade the townsfolk from here.

A 30-minute drive east of Sopron in the town of Fertőd, and near the southern shore of Neusiedl Lake, this magnificent yellow baroque and rococo palace is often referred to as the Hungarian Versailles. Built between 1720 and 1760 as a residence for the Hungarian noble family, it was badly damaged in World War II but has since been painstakingly restored. Step through the intricate wrought-iron gate entrance to discover the palace's 126 lavishly decorated rooms, including the Banqueting Hall with its ceiling fresco of Apollo in his chariot, the beautiful library with almost 22,000 volumes, and the enormous Sala Terrena with its heated marble floor. There's also a three-story-high concert hall, where classical concerts are held throughout the summer as part of the International Haydn Festival; Joseph Haydn was the court conductor to the Eszterházy family here for 30 years. Before you leave, take a walk around the ornamental French-style gardens.Not to be confused with Schloss Esterházy in Eisenstadt, also a 30-minute drive but north, not east. This was the family's main residence; see the Eisenstadt section for more.

The city's attractive main square is dominated by the early Gothic Soproni Nagyboldogasszony templom (Blessed Mary Benedictine Church), better known as the Goat Church for reasons both fantastical–-it's said the church was financed with treasure found by a billy goat–-and practical–-goats feature on the coat of arms of the actual church financiers. It's a real mishmash of styles, with a Gothic choir, a rococo main altar, and a Baroque red-marble pulpit, along with recently discovered medieval tombs. Outside stands the 18th-century Szentháromság-szobor (Holy Trinity Column), Hungary's finest plague memorial and among the first anywhere to feature a twisted column.

Facing the square are three very different but equally fascinating museums. Fabricus Ház (Fabricius House) is a beautiful Baroque mansion with exhibits on ancient city history: highlights include the remains of a Roman bathhouse and the 1,200-year-old Cunpald Goblet. The Storno Ház (Storno House) is Sopron's finest Renaissance-era building with a collection of furniture, porcelain, sculptures, and paintings belonging to the Stornos, a rags-to-riches dynasty of chimney sweeps-turned-art restorers. The Fehér Angyal Patikamúzeum (Angel Pharmacy Museum) is a real-life 17th-century apothecary that now houses a collection of period pharmaceutical tools, books, potions, and lotions.

This grand Rococo-style summer residence was built in 1780 for Count Anton Grassalkovich, advisor to Empress Maria Theresa (who was crowned in Bratislava in 1761). Today, it's the official residence of the President of the Slovak Republic so it isn't possible to see inside, but come at 1 pm any day of the week to witness the ceremonial Changing of the Guard. You can also head around the back of the palace to explore the lovely Prezidentská záhrada (Presidental Garden), a public park that's an oasis of manicured lawns, sculpted hedges, and gorgeous flower displays. It also has a number of avant garde sculptures, including the playful Fountain of Youth by Slovak sculptor Tibor Bártfay.

Bratislava's main square is the beating heart of the city, home to some of its most interesting history, architecture, and artworks. The centerpiece of the square is Maximiliánova fontána (Maximilian's Fountain), erected in 1572 as a public water supply. The knight on top is said to bow once a year, on New Year's Eve, though only for those pure of heart and born in Bratislava. The square is ringed by a number of beautiful Gothic and Baroque buildings, many of which are now embassies. The most notable of these is the Stará radnica (Old Town Hall), which is actually a mishmash of different houses built at various stages from the 14th century onwards; look for the cannonball embedded in the town hall's tower. Opposite, on the corner outside Café Mayer, is the Schöne Náci (Nice Nazi) statue, depicting a famous local eccentric who cheerfully wandered the streets in top hat and tails. As well as the permanent fixtures, the square also hosts regular markets, concerts, and political events.

This charming, tree-shaded promenade is named for renowned Slovak poet Pavol Országh Hviezdoslav and lined with some of the city's grandest buildings—now mainly embassies, hotels, and restaurants. The "square" starts with a statue of Hviezdoslav and ends at Morový stĺp, a beautiful Baroque trinity column. Just east of Hviezdoslav Square is the old Slovenské národné divadlo (Slovak National Theatre) building, while just around the corner crowds gather to see the popular Čumil (Rubberneck) sculpture; a cheeky bronze chap peeping out from under a manhole cover.

Bratislava's most striking Secession (art nouveau) style building, the Church of St. Elizabeth is noted for its powder blue exterior, which extends all the way up to its 120-foot round tower. The unusual color scheme continues throughout the early-20th-century building, from the blue ceramic roof tiles, mosaics, and maiolica (tin-glazed pottery) decorations outside, to the baby blue pews and arches inside. The church once functioned as the chapel of the school opposite, which is evident in the two buildings' similar design elements (though the school has a rather more traditional color scheme).

This medieval synagogue is now a religious museum complete with stunning stained-glass windows, a stone mikvah (a ritual bath for women), and old Torahs on display. Built around 1300, the synagogue endured several incarnations over the centuries, including a stint as a hospital (in the 1400s) and a residential building (in the 1700s); the existing facade dates from 1734. The synagogue was once at the heart of the city's Jewish ghetto, and a plaque honors the 1,640 Jews of Sopron—85% of the city's total population—who were murdered by the Nazis.

Attached to the Museum of Viticulture—which traces the long history of winemaking in the Bratislava and Lower Carpathians region—is this beautiful 16th century wine cellar offering regular tastings. The national collection is made up of Slovakia's "Top 100 Wines," which are chosen from more than 600 entries each year; you can find everything from Tokajs to ice wines. Choose to sample two, four, or eight of the collection's wines and a professional somelier will guide you through the experience. Alternatively, opt for the self-guided, all-you-can-drink "72 wines in 100 minutes" tasting. All tastings are available for individuals or groups, but it's best to call ahead to ensure an English-speaking guide.

This pretty manor house, situated 13 kilometers (eight miles) southeast of Sopron, is the family seat of the Széchenyi family. Mostly completed in the neoclassical style but heavily rebuilt after World War II, the property is now home to the Széchenyi Museum, which tells the family's story through reconstructed rooms and period furnishings. The star of the show is Count István Széchenyi, known as the "Greatest Hungarian" for his achievements as a politician, writer, reformer, and generous patron: his money helped establish the Hungarian Academy of Sciences and build the Chain Bridge in Budapest. You'll find an immodest number of István portraits throughout the property, as well as interactive exhibits on some of his projects. Information within each room is scarce for non-Hungarian speakers, so be sure to pick up an English-language brochure on your way in.

This beautiful Inner Town street runs south from Fő tér to Orsolya tér, where there's an interesting fountain showing Jesus using his crucifix to pierce a snake with an apple. As you walk down the street, you will come across an eclectic mix of architecture coexisting in a surprisingly harmonious fashion. The Erdody Vár (Erdody Palace) at No. 16 is Sopron’s richest rococo building. Two doors down, at No. 12, stands the Eggenberg Ház (Eggenberg House), where the widow of Prince Johann Eggenberg held Protestant services during the harshest days of the Counter-Reformation and beyond. Today, it's home to the Macskakő Múzeum, an interactive children's museum about the everyday lives of people living in ancient times. But the street takes its name from Szent György templom (St. George’s Church), a 14th-century Catholic church so sensitively “Baroqued” some 300 years later that its interior is still as soft as whipped cream.

Starting near the Fire Tower and following the route of Sopron's medieval town walls, the Bailey Promenade makes for a lovely stroll. The oldest part of city walls were built in the 14th century but some sights along the way are even older: look out for ancient gate foundations, remnants of the Roman town of Scarbantian. Some sections of the promenade close overnight.
