Prince Charles will accept the prestigious Vincent Scully Prize at the National Building Museum while making an official visit to Washington with his wife, Camilla, next week.

In announcing the award yesterday, the museum sought to recognize the prince's long-standing interest in architecture and urban planning.

Architect Robert A.M. Stern, dean of the Yale School of Architecture and a member of the selection committee, described the Prince of Wales as "an outspoken, highly placed, highly articulate advocate" for the preservation of landscape, the education of architects and the quality of the built environment. He added that the prince "has drawn attention to the physical environment as very few people in public life have in a generation or more."

Prince Charles, one of Britain's best-known architectural critics, is scheduled to deliver a talk Nov. 3 in the Great Hall. The event is free, but the museum's announcement advised that seats were already gone.

The prize was established six years ago to recognize "exemplary practice, scholarship or criticism" in architecture, historic preservation and urban design.

In addition to championing classical architecture, the prince has established a foundation to teach the principles of traditional urban design. A trust promotes the rescue of endangered buildings of historic and architectural value. The Prince's School of Traditional Arts has attempted to resurrect interest in arts and crafts. Many of the old skills, including stained glass, mosaics, and icon painting, cross religious and cultural boundaries, the museum noted in its announcement.

Previous winners of the Scully Prize include Jane Jacobs, Andres Duany and Elizabeth Plater-Zyberk, Robert Venturi and Denise Scott Brown, and the Aga Khan.

The prince's efforts won over the Scully Prize jurors in 2004, but no trip to pick up the award could be scheduled until now.

There will be one public component to this year's Scully Prize. The building museum will host two exhibitions organized by the prince's charities. "Civitas: Traditional Urbanism in Contemporary Practice" and "A Building Tradition: The Work of the Prince's School of Traditional Arts" will open to the public Nov. 5 and run through Jan. 8.

Prince Charles will be honored for his efforts toward historical preservation and urban planning.
