| The Green Street allotment site in Royston is probably more intensively cultivated at present than at any time in the last 30 years due to the upsurge in interest in growing one's own vegetables in recent times. When this photograph was taken on 9th July 2007 (at 1040 GMT) judging for the best kept allotment as part of 'Royston in Bloom' had recently taken place and this westward looking view from near the Coombes Hole boundary shows the winning plot in the foreground. A W'ly breeze of mean speed 2 knots gusting to 8 knots is drifting across the allotments in a temperature of 19.0°C (later rising to a maximum of 22.5°C). Sunshine for the day was 9.2 hours. | Due to some splendid floral displays over the years the Town Hall roundabout in Royston has featured in these pages on several previous occasions. The display this Summer is no exception and motorists travelling through Royston on the A10 road can hardly have failed to be impressed as they cross the ancient east-west Icknield Way at this point. This is the view looking southwards (at 0903 GMT on 22nd July 2007) along the A10 relief road built in the 1960's to remove through traffic from the High Street several hundred metres to the west. The site of the demolished Priory Cinema is to the left of the picture, and the Priory Gardens to the right. | This 'mother and baby' cameo was pictured on the Wimpole Hall estate some 10 km N of Royston on 24th July 2007 at 1139 GMT. The Wimpole Hall farm specialises in rare breeds of cattle and this pair are believed to be of the White Park breed which are characterised by their black noses, eyes and ears and long horns sweeping outwards. Also present (not pictured) with this herd were specimens of the Longhorn breed whose colours vary from red-roan through to plum-brindle; they have a distinctive white stripe down their backs and tails, and horns which curve towards the front. On the horizon the 1708 built Gothic Tower can just be detected. |
