Vaduz Castle, seen properly from the outside

The castle is the first thing you see of Vaduz and what most people look up before they come, nearly always with the same question. The short answer is no, you can’t go inside. The longer one is that it’s still worth the climb, and there’s a perfectly decent way to see the interior without crossing the threshold.

Why can’t you go in?

Because people live there. The princely house puts it plainly in its FAQ. The castle is the home of the Prince and the Hereditary Prince and Princess, so it isn’t open to the public; guided tours happen only on exceptional occasions. It’s not a seasonal palace like Monaco’s, which opens its state rooms from spring to autumn. The family lives here all year, and it has been their permanent residence since Franz Josef II moved in in 1938. Who’s who in the family is in my guide to the Prince of Liechtenstein.

One myth is worth clearing up. The flags on top don’t mean the Prince is at home. The house explains they fly every day unless the wind is strong.

A fortress that nearly slipped away

I find the building’s story more interesting than the legend. The keep dates from the 12th century, with walls about 4 m thick at the base, and the first written record is from 1322. The north-west residential tower is dated to 1287 from the wood of its beams. The Swiss Confederates burnt it in the Swabian War of 1499, it was rebuilt, and between 1523 and 1529 it gained the two round bastions you see today, designed to stand up to artillery.

The Liechtensteins bought it in 1712 along with the county of Vaduz. It housed the Landvogt, the governor, until 1732, and then nobody lived in it. The Historical Lexicon describes a neglected half-ruin that drew Rhine romantics in the 19th century, served as a prison and a barracks, and kept a tavern for visitors until 1896. Reconstruction came between 1904 and 1914, pushed by Prince Johann II and steered from Vienna. Since 1945 it has also held the store of the Prince’s art collections, a thread I pick up in the guide to the princely house of Liechtenstein.

Walking up, and what you see at the top

The castle stands on a rocky spur at 570 m, about 120 m above the centre. You walk up along the path that leaves the Städtle and continues through the woods to the Schalun castle ruin, and stage 2 of the Liechtenstein Trail, coming down from Triesenberg to Vaduz, passes by too. At the top you see the tower and the bastions up close, and below you the whole Rhine valley with the Swiss mountains opposite. That’s free and, for me, it justifies the climb.

What I wouldn’t do is try to peer through the gate or into the garden. It’s a private home, entitled to its privacy, and the walk ends at the wall.

The best view is down among the vines

This is where plenty of people get it wrong. They go up to the castle, come down and leave, missing the good view. From the Mitteldorf, north of the centre, with the Red House in Vaduz and the vines in front, the castle appears clinging to its rock with the woods behind. The Citytrain stops there for exactly that shot. With time for just one of the two, I’d pick the vineyards.

Seeing the interior at the Altes Kino

The alternative the tourist board itself offers is a film. The Altes Kino in Vaduz shows «Fürstliche Momente» every day at 14:00, 20 minutes of footage from inside and of life behind the walls. It’s free with the ALL INCLUSIVE Adventure Pass, and the Citytrain sells it combined with its town loop for CHF 22 an adult. It isn’t the same as walking the rooms, but it’s as close as you’ll get.

The day the castle opens its garden

There’s one day a year when the grounds fill with people. On 15 August, national day, the state ceremony has been held since 1991 on the meadow beside the castle, and afterwards the Prince invites those attending to drinks in the garden. In 2026 the 10:30 ceremony was ticketed and sold out, and there were no fireworks because of a total ban on fires. If you want to be there, check the programme early in my guide to Liechtenstein’s national day.
