Mottisfont Abbey Garden
The archetypal English rose garden overflowing with gorgeous old varieties. You can still see the ruins of the 13th-century abbey, but the highlight is the National Collection of old-fashioned roses. Visit on a weekday or evening if you can as it gets very busy on summer weekends.
