The Queen and the Duke of Edinburgh will be in Pembrokeshire next Thursday, November 22, for a day-long visit.
During their seven-hour stay, the royal couple will be visiting several locations in North, Mid and South Pembrokeshire and, in parts, will follow separate itineraries.
The centrepiece of the visit is the opening by Her Majesty of County Hall, the £10 million headquarters of Pembrokeshire County Council alongside the River Cleddau in Haverfordwest.
The authority's chairman, Clr. Mrs. Rosemary Hayes, said the visit was a great honour for Pembrokeshire.
She added: "The Queen's engagement diary is extremely full, bearing in mind that she is to celebrate her Golden Jubilee in 2002.
"Her Majesty is unable to come to Pembrokeshire next year. However, she was keen to return to Pembrokeshire and this is how the visit came about.
"This will be an exciting day for the county and I hope that thousands of people will be out on the streets to give the usual warm Pembrokeshire welcome to our royal guests."
The couple will arrive in Haverfordwest by Royal Train soon after 10 am when they will be welcomed to the county by the Lord Lieutenant of Dyfed, Sir David Mansel Lewis, and other dignitaries.
The Queen will then depart separately for an hour-long visit to St. Davids where she will open the newly-restored Gatehouse and Bell Tower, Porth y Twr.
At approximately 11 am, Her Majesty will enter St. Davids Cathedral and will meet cathedral lay staff and helpers in the Nave.
She will be accompanied by the Dean of St. Davids, the Very Reverend Wyn Evans, to the Quire where Her Majesty will sit in her stall and listen to an item especially composed for the visit by the cathedral organist, Mr. Timothy Noon.
During the Queen's tour of the cathedral, representatives of the agricultural, tourism, artistic and craft communities will also be presented to her.
Prior to her departure for Haverfordwest at approximately 11.45 am, Her Majesty will sign the visitors book.
While the Queen is in St. Davids, the Duke of Edinburgh will be visiting the family-run Oakwood Leisure Park, near Canaston Bridge.
At approximately 10.30 am he will meet the McNamara family who established the park in the mid-1980s when they left the agricultural industry on the introduction of milk quotas.
His Royal Highness will be taken on a short tour of the park before meeting representatives of other successful farm diversifications, including Folly Farm, Upton Farm Ice Cream, Cwmderi Vineyard, Princes Gate Spring Water and Bakeaway Bakery.
Before rejoining the Queen, the Duke of Edinburgh will tour the popular Pembrokeshire Farmers' Market at Riverside Quay, Haverfordwest, arriving at approximately 11.30 am.
The couple are expected at County Hall, Haverfordwest, shortly after noon when, weather permitting, they will meet members of the public in a walkabout on the car park in front of the building.
Prior to the arrival of the royal party, the 37-strong Band of Her Majesty's Royal Marines will provide music and a marching display in the County Hall car park. Based at the Commando Training Centre Royal Marines at Lympstone in Devon, the band will be led by its director of music, Captain Nick Grace.
The Queen and The Duke will be welcomed by the chairman, Clr. Mrs. Hayes, before the Queen unveils a plaque to open County Hall.
Following lunch for approximately 80 guests, the couple will depart the building at around 2.15 pm for separate locations in Pembroke Dock.
The Queen will leave County Hall and drive through Haverfordwest town centre en route to Pembroke Dock which she will enter via London Road, Water Street, Laws Street and Bush Street.
The Queen will be greeted at the Pembroke Dock Community School by the leader of Pembrokeshire County Council, Clr. Maurice Hughes.
Accompanied by the headteacher, Mr. David Thorley, she will move through the school, visiting classrooms and viewing examples of the work of pupils.
Her Majesty will also visit the school's Sensory Room, specially designed for autistic children, before officially opening the school by unveiling a plaque.
Meanwhile, the Duke will visit the 25-acre Pembrokeshire Science and Technology Park overlooking the Milford Haven waterway at the Cleddau Bridge.
The hi-tech park is the result of a collaboration between Pembrokeshire County Council and the Welsh Development Agency.
The Duke will tour the ITV Digital Customer Contact Centre which employs over 800 people. Before leaving he will unveil a commemorative plaque.
At around 3 pm, the Queen and the Duke will arrive at Pembroke Castle for a garden party in a huge marquee erected in the ground, the royal convoy arriving by turning right at the bottom of Northgate Street (known locally as The Dark Lane) and into Castle Terrace.
They will be welcomed by Major Ivor Ramsden, manager, and Mrs. Ramsden, chairman of the Pembroke Castle Trust.
Some 400 guests have been invited, representing a wide range of organisations, charities, business, industry and other aspects of Pembrokeshire life.
The couple will leave Pembrokeshire at approximately 4 pm.
