The abbey of the Augustinian Canons at Herzogenburg with its 70-metre tower is visible from miles around. The baroque abbey church designed by Jakob Prandtauer and Fischer von Erlach ranks among the most important late baroque buildings in Austria.

Ardagger abbey near the Danube is home to an exceptional work of art: the "Margarethenfenster" (St. Margaret's window) is the oldest figural stained glass window in the German-speaking area. Equally impressive are the cloisters and the sundial, which shows so-called "Italian and Babylonian hours“ as well as standard local time.

Seitenstetten abbey, a baroque gem in a magnificent setting, is often called "God's four-sider" in reference to the typical layout of the local Mostviertel farmsteads. In 1620 Austria's first ever potatoes were cultivated here. There are regular guided tours of the abbey, and the historic courtyard garden is a lovely spot for a stroll or to sit and relax for a while.

Visible for miles around, the twin-towered baroque church that perches atop the 700-metre Sonntagberg dates from the 18th century. It was designed and started by Jakob Prandtauer and completed by Josef Muggenast. The frescoes, the treasury and the high altar are especially worthy of note.

The largest Carthusian monastery in Central Europe, at Gaming, was built in 1342 and secularised in the 18th century. Situated at the gateway to the Mostviertel mountains, the building complex has been renovated in an exemplary manner and houses remarkable art treasures, a hotel, function rooms and a restaurant.

The Cistercian abbey of Lilienfeld is over 800 years old. Central Europe's most monumental mediaeval monastery complex is the repository of the first ever official seal bearing the Austrian national coat of arms. Baroque extensions were added to the abbey in the 17th century.
