Q2. The Battle of Cropredy Bridge
The initial clues appear to place us at Coombe Abbey, Brinklow Road, Binley, Warwickshire CV3 2AB. The Abbey, which was founded c 1150 AD according to some of the sources I checked, now seems to be a very luxurious hotel and indeed has a room which was once occupied by princess Elizabeth Stuart (born c 1596), who was the daughter of James VI of Scotland. The princess lived at the abbey for a time under the care of Lord Harrington and his wife, later marrying Frederick V, 'count Palatine of the Rhine and elector of the Holy Roman Empire'. Princess Elizabeth was promoted to 'Queen of Bohemia' upon the wedding and was known as the 'Winter Queen', due to an insurgency cutting short her husband's tenure of employment in that region.

Travelling south from Coombe Abbey would bring us to the twenty two acre organic gardens at Ryton, which seem to have been opened c 1980s . They also practice biodynamic organic gardening there, which is organic horticulture with a bit of Theosophic/Anthroposophic hocus pocus a la Rudolf Steiner, thrown in for good measure.
