Prince Charles has offered his parents a look at Poundbury, the planned community built using principles for which he advocated and that gives priority to people instead of cars.

Queen Elizabeth II gave her stamp of approval to the project as she unveiled a statue of her mother at the newly christened Queen Mother Square.

The project, which began in 1993, mixes commercial and residential property to create a community made for walking. It includes shops, cottages and homes that reflect Charles' passion for classical architecture.

Andrew Hamilton, development director for the Duchy of Cornwall, which owns the land Poundbury is built on, said at the statue's unveiling that Charles "single-handedly set out to challenge the accepted orthodoxy of planning and development in this country."
