The Herbaceous Garden at Anglesey Abbey (28 km NE of Royston) must be one of the best of its kind in East Anglia, being formed around a large semi-circular lawn framed by mature beech hedges. This picture shows a part of the curved section (the whole border being over 200 metres long) and is as seen at 1103 GMT on 4th July 2006. A statue (not shown) of the Saxon god 'TIW' by J. M. Rysbrack (1694-1770) is placed at the centre of the pristine green lawn. The many varieties of plants include an impressive display of  delphiniums arranged in groups around the border. The day was hot, the maximum temperature at Royston reaching 29.7°C, whilst sunshine for the day was 7.9 hours. This picture (taken from the terraced walk at 1416 GMT on 11th July 2006) shows the south front of the Rotunda at Ickworth House (50 km ENE of Royston). The extraordinary central Rotunda is but part of Ickworth House, which was created (from 1795) by Frederick, 4th Earl of Bristol and Bishop of Derry and was inspired by the monuments of Rome. Unfortunately the Earl-Bishop's wife was not impressed and condemned Ickworth as a 'stupendous monument of folly'! Apart from varying lighting conditions this particular scene looks much the same at any time of the year given the choice of coniferous shrubs and trees on display. As indicated in the picture it was a sunny day with 12.3 hours sunshine at Royston. On 19th July 2006 the temperature at Royston reached 35.2°C, its highest value in July since at least 1972. On this day, during harvesting operations at Lowerfield, some 2 km E of Royston, a devastating fire took hold and destroyed about 40 acres of standing barley and oilseed rape, as well as straw awaiting collection and stubble. The fire also badly scorched the mature belt of trees and bushes shown here, and it remains to be seen if the larger specimens can survive this total leaf loss. This photograph was taken 11 days later on 30th July (at 0817 GMT). The blackened appearance of the fields after the fire is not apparent here as torrential rain during an evening thunderstorm on 26th July has largely cleansed the soil.
