With the sensational turnout and massive show of enthusiasm for all Jubilee events so far, and huge support for the Olympic Torch Relay, organisers are looking forward to a bumper turnout on Wednesday, July 11.
Organiser Mike Smart said: "With the fantastic interest in the Diamond Jubilee, we're expecting that the people of Herefordshire will turn out in force to support the event on July 11.
“A Diamond Jubilee is a once-in-a-lifetime event and we're going to make it a day to remember for everyone and having Her Majesty and the Duke of Edinburgh coming to Hereford is a fantastic honour”.
Finishing touches are being made to the day's attractions - the theme of the day is to celebrate all that is good and great about Herefordshire and will include performances by dancers, musicians and choirs from all over the county.
One star attraction will be the Wye Trow, the 36ft replica working boat which took part in the Queen's Jubilee Pageant on the Thames earlier this month.
Visitors will be able to see the boat up close and personal and talk to members of the crew about their experiences at the Pageant.
