| This famous Royston landmark is King James Palace in Kneesworth Street, as photographed in the late afternoon sunshine on 28th June 2010. When King James VI of Scotland travelled south in 1603 to accede to the English throne (as James I) he is said to have stopped in Royston on the way, and duly impressed later set up court in the town to indulge in his passion for hunting. A number of other houses were built in the vicinity of the Palace to support the King and his court; the barely discernible building to the right of the picture housed the King's kitchens, and opposite is another building which accommodated the King's equerries. At the time of the photograph (1545 GMT) the temperature was 27.2°C, just short of the day's maximum of 27.7°C. A total of 14.9 hours sunshine was enjoyed in Royston on this day. | This is one of the many colourful views in the magnificent Garden of the Rose at the home of the Royal National Rose Society at Chiswell Green just to the SW of the city of St. Albans, and some 41 km to the SSW of Royston. After temporary closure several years ago the Garden was completely refurbished and re-opened with new roses on 9th June 2007. The gardens boast stunning displays of tens of thousands of roses, both old and modern, complemented by companion plants such as herbaceous perennials, spring bulbs, shrubs and grasses. On the day this photograph was taken (3rd July 2010 at 1331 GMT) the gardens had just experienced a very dry June as evidenced by the parched grass areas. This was followed by an equally dry July, thus delaying recovery of the grass to the normal lush green. | A combination of cumulus and cirrus clouds plus a number of aircraft contrails makes for an interesting sky over Royston in the early morning of 10th July 2010 (at 0744 GMT). This was the view from the Icknield Way at Lowerfield some 2.5 km E of Royston and features an acreage of oats approaching maturity. Harvesting of this crop commenced some 12 days later in what had been a very warm and dry July to date. The temperature at this time was already as high as 21.6°C, later rising to a maximum of 29.6°C. On the previous day the temperature had attained a maximum of 31.3°C, this being the first day to reach 30°C for 4 years (since 26th July 2006). The oats are gently swaying in a S wind of mean speed 5 knots gusting to 10 knots, and a sunshine total of 14.1 hours for the day undoubtedly assisted the ripening process of this crop. |
