Rowton castle is a great venue for a wedding and it looks really good with the snow.

The only issue with winter wedding is the surprise arrival of snow/ice which means that guests may find transport tricky.
So try to plan for this and encourage guests to stay over for the weekend.But they can be very beautiful and have a magical quality. A white theme can be stunning, and at least you know it will be cold so you can add lots of winter warmer touches for guests like cosy hand warmers for the church.
