Schloss Ahrenthal

Sinzig, Germany, Germany

---

Schloss Ahrenthal in Sinzig, Germany, is a historic castle built around 1890, nestled amid forests and vineyards in the Ahrtal region between Cologne and Frankfurt, originally part of a larger estate designed by architect Johann Adam Breunig for the Hillesheim family before passing to the Counts of Spee in 1804.

Today it functions primarily as a modern seminar and conference venue under Châteauform management, offering 15 high-tech daylight-flooded meeting rooms for up to 90 people, 65 Nordic-style guest rooms, a converted chapel lounge, wellness facilities like a gym and sauna, and cuisine blending regional and Mediterranean flavors using on-site forest herbs.

Surrounded by its own managed woodlands that supply biomass heating, the property provides a serene, productive retreat for events, team-building, and relaxation near the Rhine.
