By guided tour only. Château de Brissac is a current residence for the Brissac family that counts…read moreVeuve Clicquot among their ancestors. The château has seven stories altogether, making it the tallest château in the Loire Valley. The front of the house is an interesting combination of medieval castle and 17th century's Baroque architecture The house is lovely and still holds gorgeous artwork of the family, furniture and tapestries from the centuries and we got to see their own theatre where they would put on plays and recitals. Large kitchen underground where I understand they offer cooking classes Their grounds have several paths to tour us around the expansive property. We saw their stables and vineyards. We also went into their underground tunnel. Very cool We walked right up & got into their next tour - it was french but english translations were handed out & since the majority of the group were english-speakers, the guide offered commentary in both languages. Very nice of him!
