3 Best Sights in Day Trips from Vienna, Austria

This great Augustinian abbey dominates the town. The structure has undergone many changes since the abbey was established in 1114, most recently in 1892, when Friedrich Schmidt, architect of Vienna's City Hall, added neo-Gothic embellishments to its two identifying towers. Inside the abbey church, treasures include the carved-wood choir loft and oratory, the large 17th-century organ, beautifully enameled 1181 Verdun Altar in the Leopold Chapel, stained-glass windows from the 14th and 15th centuries, and a Romanesque candelabra from the 12th century. In an adjacent outbuilding there's a huge wine cask over which people slide; the exercise, called Fasslrutsch'n, takes place during the Leopoldiweinkost, the wine tasting around St. Leopold's Day on November 15. The Stiftskeller, with its atmospheric underground rooms, serves standard Austrian fare and wine bearing the Klosterneuburg label. There are several different tours available covering religious artifacts, imperial rooms and treasures, wine making, and the garden.

Guided tours are in German, but audio guides with English and other languages are available.

Part palace, part monastery, part opera set, this masterpiece of Baroque architecture looms high above the Danube thanks to its upward-reaching twin towers, its grand 208-foot-high dome, and, of course, its site high up on a rocky outcrop. The Benedictine abbey has a history that extends back to its establishment in 1089, but the glorious building you see today is architect Jakob Prandtauer's reconstruction, completed in 1736, in which some earlier elements are incorporated.

A tour of the building includes the main public rooms: a magnificent library, with more than 100,000 books, nearly 2,000 manuscripts, and a superb ceiling fresco by the master Paul Troger; the Marmorsaal, whose windows on both sides enhance the ceiling frescoes and give them a curved effect; and the glorious Stiftskirche (abbey church) of Saints Peter and Paul, an exquisite example of the Baroque style. Look out for some quirky features along the way, like a "reusable coffin" that subtly opens at the bottom, and the hidden door in the library. There are guided tours in English every day at 3 pm. Take time to explore the gardens, a lovely mix of manicured lawns and wild woodland with amazing river views.

Located 14 kilometers (8½ miles) southeast of Linz, this palatial Augustinian abbey—one of the most spectacular Baroque showpieces in Austria—was built in 1686 to honor the spot on the River Enns where St. Florian was drowned by pagans in 304. Landmarked by three gigantic "candle-snuffer" cupolas, it's centered on a mammoth Marmorsaal (Marble Hall), covered with frescoes honoring Prince Eugene of Savoy's defeat of the Turks, and a sumptuous library filled with 140,000 volumes. Guided tours of the abbey also take in the magnificent, three-story figural gateway, covered with symbolic statues; the Kaiserzimmer, a suite of 13 opulent salons with the "terrifying bed" of Prince Eugene (it's adorned with wood-carved figures of captives); and the over-the-top abbey church, home to an enormous organ once played by composer Anton Bruckner. You'll also see one of the great masterworks of the Austrian Baroque, Jakob Prandtauer's Eagle Fountain Courtyard, with its richly sculpted figures. If you find one day isn't enough to see it all, there are also rooms where you can spend the night in the abbey grounds (from €104 per night, including breakfast). Getting to the abbey is easy: there are regular buses from Linz's Volksgarten.
