WASHINGTON - Visitors flowed into the U.S. Botanic Garden Conservatory as the building reopened to the public after years of renovation and further delay due the anthrax incidents on Capitol Hill.

The $33.5 million renovation includes all new plant exhibits that include nearly 4,000 living specimens. Behind the scenes is a state-of-the-art completely automated environmental control system. Computers can monitor the outside weather and automatically control misting, shade cloth, fans, air-handling equipment, heat, and window vents to achieve a perfect range of day and night temperature and humidity.

The superstructure, limestone facade, fountains, radiator, glazing system, and all exterior windows and doors have been restored or refabricated according to the original design of the building. The Palm House structure, now called the Jungle, has been recreated to the original design, but also now includes a visitor walkway at 24 feet above the floor accessible by both stairs and elevator.

"It's a place for contemplation, to feed the soul and appreciate life," said Landscape Architect for the U.S. Capitol, Matthew Evans.
