Tower
66 m
Great view over Épernay

Champagne de Castellane is a Champagne house in Epernay. A bonus tip from the source is to go up its 66-metre-high tower for a great view of Epernay and the surrounding area (source: Epernay - Top 5 things to do.md).
Note that the De Castellane cellars are temporarily closed to the public, though the 66 m tower and heritage tours still run (verified 2026-06) (source: epernay.md). The central Hôtel Jean Moët is about 1 km away (source: Hotel Jean Moët.md).
The cellars are temporarily closed, but the 66-metre tower and heritage tours still run — climb it for a sweeping view over Épernay.
Tower yes; cellars closed for now.
