Hot house/Orangery/glasshouse

I'm not sure what they classed this as. It was in the lovely garden of Castle Ashby where we went to a craft fair today. The vine is a Jasmine and looks to be quite old. In the Kitchen Garden there was an ancient Mulberry tree dating back to 1796! I took a photograph but I liked this one better. It was a gnarly old tree - I may go back and blip that later in the season - it's only just sprouting now.
The sun was lovely still today but there was a chilly wind which kept the temperature down. Finally finished all my pots so I can focus on the veg garden this week!
