Heslington Hall is the name of the York building. It's Jacobean and sits at one end of the campus next to pretty Heslington Village, which has a cafe, bank, two lovely pubs and a post office.
Can't understand why people criticise York campus. The plate glass cubes are not the loveliest, but sit quite graciously betwixt maturing Willows and well thought out parkland - great for blanket on the ground, summer picnics.
The fact that it's entirely low rise is a plus, I think.
There's a focal point in the futuristic spaceship like central hall, which squats on an artificial lake containing a fountain. Paths criss-cross this central area, giving the place a sense of community as you will always bump into somebody you know, coming and going.
The wildlife creates hazards - watch out for duck poo if scootering - but can be fascinating. Watching ducklings trying to negotiate the water features, supervised by parents, then succeeding, is delightful!
There's even a campus mascot, called Longboy. A long necked goose, whose strutting around the place is a source of much mirth.
One of the main problems, IMO, is that many students will have applied to Oxbridge and wanted the "dreaming spires" experience. York city, easily walkable from campus, has history in abundance and dreaming spires aplenty. The city itself, IMO, has more to offer than either Oxford or Cambridge centres.
