Blickling Hall, North Norfolk - NOT amateur radio

Oriental Plane Tree?

This afternoon we drove to North Norfolk to the National Trust property at Blickling Hall. We'd been several times before and only went into the gardens. All the driving really tired me, so I sat on a bench in the shade whilst my wife took photos. I think this was an oriental plane that I sat under. It had seeds a bit like sweet chestnuts but the leaves were all wrong.
