While we're complaining about triple-digit temperatures and rummaging through our closets to find anything comfortable to wear, Burton Barr Central Library preps for its coolest event of the year. At the stroke of noon every June 21, the library opens its doors to the public for a unique natural light show. When the library was designed by Will Bruder, the architect included a Great Reading Room with a 32-foot suspended ceiling and several 6-inch-by-300-foot skylights on the east and west walls that work together to create a dazzling spectacle every Summer Solstice. Call it a good excuse to ditch the office or an impressive lunch date, we'll be marking our calendars for a cultural escape from the heat.
