On our Castle Authenticity Scale that breaks down as one true castle, 10 castle-style mansions, four castle estate stays, one historic house, one castle in name only and one still being checked.

Questions

Do castle spas open to non-residents?

Some do and some keep the spa for hotel guests only. Access, opening hours and whether treatments must be booked ahead vary by hotel. Check the spa page of the hotel you are considering, especially at weekends when day guests can fill the treatment diary.
