Plenty of Vienna’s lesser-known architectural treasures remain inaccessible to the public. Which is bad luck for us. Except on one weekend a year, when the Open House Wien initiative invites you to tour dozens of them for free.
- Supervised tours of interesting houses, workplaces, and industrial buildings
- Often the only time a building opens to the public
- 2025 dates: Sept 13-14

Think of Vienna and you probably think of palaces, museums, churches and, possibly, chocolate cake. But this is a city of almost two million people, and most of us don’t live or work in a Baroque masterpiece (sadly).
Nor has architecture stood still since someone decided to build a nice place in the country for Eleonore of Gonzaga in 1642.
Open House Wien (Open House Vienna) introduces you to some of the architectural jewels that may not feature quite so often on tourist maps. Each has its own attraction, whether innovative design, historical importance, or relevance to some prevailing issue of the day.
So you might discover some of the public housing gems created during the 20th century, look inside a 19th-century factory once famous for its piano manufacture, or view futuristic buildings put up only recently.
One year, I used the Open House opportunity to take a look at an early example of a council flat with a fitted kitchen (far more interesting than that perhaps sounds).
The event is only made possible by the kindness of participating institutions and, particularly, the efforts of dozens of volunteers. It’s all part of a wider initiative, Open House Worldwide, which began in 1992 in London.
Dates, tickets & tips
The 2025 edition looks set to run across the weekend of September 13th and 14th.
Watch for listings at the Open House Wien website and plan your tours accordingly. To give you an idea of what to expect, around 55 locations participated in 2024.
(Note that some places may be in the surrounding province of Lower Austria and some may open on one day only, rather than on both days.)
You don’t need a ticket, because the event’s free. However, most tours are inevitably in German and you may have to wait at a location for the next tour slot.
A couple of tips:
- Pick those locations where the visual component is most important to you, then it doesn’t matter which language the tour is in
- A similar event is European Heritage Day (usually at the end of September), though typically covering the kind of buildings that have preservation orders on them
- And if you’re looking to tour some of the more prominent historical buildings the rest of the year, then consider this collection of guided and in-house tour options.
