The big house by the entrance is a Regency beauty, fallen on hard times, with not a lot of land around it, considering the sort of house it is. Here it is.
It could well have been the head brewer's - the brewery long predates the Harp Lager connection. I think at some point it may have been used as office space.
The old Maltings, a short walk from the brewery site, have been beautifully modernised and adapted, and are now run by a church as their place of worship and an arts venue - I've seen some nice, simple, opera stagings there, and even performed there myself (not folk as such - guitar and voice with a musical theatre group).
