Where Ships Moor

Grein has two landing stages on the Danube, and your cruise line will tell you which one your ship uses. The town square, Stadtplatz, with the historic theater at No. 7, is the natural place to start, and Greinburg Castle stands on a rock above the town.

  • Grein has about 2,930 inhabitants and is the easternmost town in Upper Austria, 55 km east of Linz.
  • At 239 meters above sea level, it is also the lowest-lying town in Upper Austria.
  • The signposted walking routes start from a hiking information point on the riverside, the Donaulände.
  • Grein Stadt station is on the railway along the Danube bank, and a post bus runs to Amstetten in about half an hour.
  • In the summer months a ferry for cyclists and pedestrians crosses to the south bank of the river.

Grein on Your Own

Grein's sights are its town square, the old theater in the former town hall and the castle above the town. A simple plan is the square and the theater first, then the castle, and a look at the sundial by the harbor on the way back to the ship.

  • The town square: The old town hall, finished around 1563, keeps its original form, and an eight-sided stone fountain from about 1600 stands on the square. Many of the surrounding houses have baroque facades on long medieval plots, rebuilt after a town fire in 1642.
  • The theater: In 1791 the townspeople fitted out the town hall's grain store as a rococo theater with 167 seats. The front rows still have their original lockable seats, and a toilet is separated from the auditorium only by a curtain. From May to September it opens for visits from Monday to Saturday, with a town museum in the same building.
  • Greinburg Castle: The castle stands on the Hohenstein, a granite rock above the town. A visit takes in the arcaded courtyard, a great hall 30 meters long, the chapel and the Sala terrena, a room decorated entirely with mosaics of Danube pebbles. It opens from Tuesday to Sunday between May and late October, and an adult ticket cost €9 in 2026, so check before you go.
  • The sundial: A precision sundial with a stainless-steel ring 4.17 meters across stands at the Römerrastplatz in Grein's harbor, open at all hours. Its dial shows the date as well as the time.
  • Getting back on time: All-aboard is usually about 30 minutes before sailing, and your ship posts the exact time. A ship will not wait for passengers touring on their own.
  • Carry your passport: Austrian law requires you to have easy access to your passport at all times, and a copy of the photo page is helpful.

Tipping in Austria

Tipping is customary in Austria, and although the law does not require it, many people see it as expected. In restaurants 5 to 10 percent of the bill is common, and the currency is the euro.

  • Taxi drivers are usually tipped too, often by rounding the fare up to the next euro.
  • Do not offer a tip to a government employee, since it may be taken as a bribe.

Theater, Music and the River

Theater has been part of Grein's life since 1791, and the old town theater is still played from March to December. In summer the castle is a regular venue of a music festival held in the Strudengau since 1995.

  • An amateur company, the Greiner Dilettantengesellschaft, has used the theater as one of its stages since 1992.
  • Besides plays, the theater puts on concerts and readings.
  • The Donaufestwochen im Strudengau, held since 1995, use Greinburg Castle as a fixed venue.
  • Since 2011 the town cinema has hosted the danubeVIDEOARTfestival, a festival of video art.
  • The Danube Cycle Path runs through the town, and the long-distance Donausteig trail passes above it.

A Brief History

Grein grew on Danube shipping, beside a narrow stretch of the river whose rocks and whirlpools made it one of the most dangerous on the Danube. It became a town in 1491, gained its castle in the same years, and later passed into the hands of the dukes of Saxe-Coburg and Gotha.

  • First record, 1147: Grein is first mentioned in 1147, when the monastery of Säbnich, later Waldhausen Abbey, was founded. Under the Babenberg dukes the town prospered from river traffic, with licensed boatmen and sworn pilots for the narrows downstream.
  • A dangerous river: The Strudengau, the narrow valley of about 25 km in which Grein lies, had rocky reefs that threw up roaring whirlpools. The danger ended only in 1957, when the Ybbs-Persenbeug power station dammed the river. The town's name is usually traced to an old word for shouting, for the roar of the water or the cries of boatmen, though that may be folk etymology.
  • Fire, a castle and town rights: Grein burned in 1476 during the Bohemian wars. In 1488 Emperor Frederick III allowed the brothers Heinrich and Siegmund Prüschenk to build a castle on the Hohenstein rock, and in 1491 he raised Grein to a town.
  • Reformation and fire: Around 1600 many citizens were Lutheran, and in 1599 some had to leave the town because of their faith. A great fire devastated Grein in 1642.
  • A theater for the poor, 1791: After Emperor Joseph II's poor-relief reforms allowed plays to be staged for the benefit of the poor, a local bookbinder proposed performances in 1790. The town hall's grain store became a theater the following year.
  • The Coburgs, 1823: Duke Ernest I of Saxe-Coburg and Gotha bought the castle in 1823. His sons inherited it, among them Prince Albert, so Queen Victoria later became a co-owner, and the family foundation still owns the castle.
  • War and occupation: In 1944 and February 1945 a subcamp of the Mauthausen concentration camp held about 120 prisoners in the Lettentalkeller in Grein. After a short American occupation, Grein lay in the Soviet zone from 9 May 1945 until 1955.
  • To learn more ashore: The town museum in the theater building on Stadtplatz 7 covers the history of Grein and of the theater itself.

Grein with Children

Grein suits a short family outing: a sundial and a river ferry for younger children, a theater with surprises for school-age children, and a lookout tower or a gorge walk for older ones.

  • Younger children: The sundial in the harbor is open at all hours, and in summer the ferry for pedestrians and cyclists makes a short trip across the Danube.
  • School age: The theater's guided tour for school groups suits pupils from age 6 and is adapted to their age, and tours are booked in advance. Greinburg Castle has a family ticket for two adults and children up to 16, which cost €18 in 2026, so check before you go.
  • Teenagers: The Gobelwarte, a 21-meter steel viewing tower at 484 meters above sea level on the Donausteig trail, is open at all times; the platform sways slightly by design.
  • For keen walkers: The Stillensteinklamm, a gorge about 200 meters deep, begins about 2 km east of the town center. The full signposted loop from the riverside is 15.3 km and takes about four and a half hours, so on a port day walk only as far as your time allows.

Accessible Travel

The historic theater on the town square has step-free access and a lift. The castle stands on a rock that falls away steeply on all sides, so ask the castle office about access before you go.

  • The theater has a step-free entrance and a lift reachable without steps or thresholds, with a cabin larger than 110 by 140 cm, a door at least 80 cm wide and controls at 85 cm.
  • An accessible toilet is available in the theater building.
  • Parking is available at the foot of the castle rock.
  • The paths to the Gobelwarte and through the Stillensteinklamm are hiking trails that need good footwear and are not advised in wet or snowy conditions.
