A number of ceremonies are planned
in Lockerbie throughout the day
Special "places to remember" are being opened in Lockerbie, with a wreath-laying ceremony taking place at the Dryfesdale Ceremony.
In the evening there will be services at both the Tundergarth and Dryfesdale Church.
A little after 1900 GMT the exact anniversary of the atrocity will be remembered.
For many who lived through it, the memories remain fresh despite the time which has passed.

"Once I got into Sherwood Crescent I could see flames along the roadside, the footpaths were burst and there were gas pipes fractured - there were dancing flames coming up from them.
"Hedges were on fire, drop pipes on the side of houses were on fire and they were in turn climbing up and setting fire to the roofs."
It was only later in the evening that the scale of the death toll at Lockerbie began to emerge.[here]
