Twenty-five kilometres south of Vienna, Schloss Schönau is a privately owned Habsburg castle with a 30-hectare park, an 18th-century underground grotto, and full exclusive use for weddings of up to 260 guests.
Schloss Schönau has been receiving significant occasions for centuries — royal Habsburg events are documented in the castle's history — and in 2025 the World Luxury Travel Awards named it the Best Wedding Venue in Austria. Neither fact is incidental. The castle sits in a 30-hectare park that is protected both as a nature reserve and as a federal monument, and within it stands one of the most unusual spaces in Austrian wedding hospitality: the Tempel der Nacht, an 18th-century underground grotto built in the Enlightenment tradition, with astronomy-inspired architecture and an atmosphere that no decorator could replicate.
For the wedding itself, Schloss Schönau operates on full exclusive use. The Festsaal seats a hundred for dinner; a bespoke sailcloth marquee in the park stretches to 260. The rose garden ceremony space overlooks the castle pond; ancient trees canopy other outdoor options. The estate's ten bedrooms — five castle suites and four hunting lodge apartments — keep the wedding party together from the night before through to the morning after.
