One of the round ceiling windows at the Museum of Scotland

The Museum windows perform numerous functions. While many frame views of the city, or internal views, those in the roof might be argued to be amongst the most important. The building draws heavily on ambient daylight to complete project. In this way the changing weather outside influences the amount of light within the building. This effects the light available to view exhibits, and on a day of contrasts can throw the same exhibit first into darkness, before then illuminating it in the brightest sunlight. The internal shapes of the building also receive light in multifarious ways, from both ceiling, and wall windows. The light levels are cleverly controlled throughout the building, from the murky depths of prehistory in the basement, to the bright white light of the industrial and technologically driven displays in the upper levels.
