in order to meet the national park services' objectives of sustainability, energy conservation, and 'green' design, several historic landmarks and sites are receiving 'lighting makeovers,' as part of larger, more comprehensive restorations. One such landmark is the Bunker Hill Monument in Charlestown, Massachusetts, site of the first major battle of the American Revolution.

The goals of the project are to 'provide improved accessibility to the monument, illuminate the historic site for all to see at night, and to preserve the site for future generations.' The 221-foot-tall obelisk was built between 1825 and 1843 and is the oldest major monument in the United States. And despite an annual stream of visitors numbering close to 200,000, the historic site-which includes the monument, the Bunker Hill Lodge, and an adjacent visitor's museum-has not undergone any extensive rehabilitation in almost a century.

The lighting design, prepared by Ripman Lighting Design in Belmont, Massachusetts, calls for the monument's exterior to be lit with 150W ceramic metal halide lamps arranged in clusters to illuminate the upper portion of the obelisk and the main shaft. The base of the monument will also be lit with 150W ceramic metal halide lamps to provide an even wash of light down to grade, each face illuminated asymmetrically from left to right in order to render the monument's form.

Lighting manufacturer Osram Sylvania will donate the lamps. This is one of several projects in the Boston area, including the Old State House, that the Danvers, Massachuetts-based company has played an active part in sponsoring the relighting efforts. The project is slated to start at the end of September, and last approximately 18 months. A|L
