The annual competition recognises the time spent by local traders putting on a festive show in their windows.
It is judged by the Mayor of Christchurch, who this year is Cllr Peter Hall. The cup and certificate was presented to Susie Stewart, Christmas manager at Stewarts GardenLands, by president of the Chamber of Trade, Peter Watson-Lee.
Stewart said: "We love Christmas at Stewarts, it is hard work for all the staff but we really enjoy giving so much pleasure to our customers who return annually to view our Christmas displays. It is an honour to win this award."
