I think Stonehenge is the clear and obvious winner on this one ... though the medal should be a retrospective honour and perhaps more in keeping to make it Bronze rather than Gold.
Facilities = Stonehenge wins for it soulless car park and toilets built on top of the site of post holes. Not to mention the tacky gift shop.
Statements = too numerous to mention, along with all the 'false dawns' along the way to improvements.
Reports/Publications = (As above) definitely a clear, overall winner.
Interpretation = LOL! Your guess is as good as mine but that hasn't stopped numerous experts having a go.
Special award: I would give this to Rosemary Hill for her accessible account of Stonehenge published in 2008. Factual, informative, unjargonistic, and written in clear English. She can have the 'gold' if there is a spare going.
