Travellers going to a steam festival have set up camp illegally in a field after they said they were unhappy with one they had been provided with.
The temporary base at the Sunrise Business Centre was provided by North Dorset District Council for travellers visiting the Great Dorset Steam fair.
But the group said they were unhappy with it and went into a freshly laid field 100m (109yd) away.
Council bosses say they hope to move the group on as soon as possible.
A herd of cows was due to be moved onto the field this week, but farmers fear it will now need to be re-dug.
The Great Dorset Steam Fair is intended to give the public an insight into what the English way of life looked like in the country at the turn of the century - when steam power was the most modern technology.
