When I saw the hole in the wall for the summer solstice sun at the Hagar Qim temple in Malta, it reminded me that many ancient monuments were designed to allow the sun to enter at certain times of the year and to illuminate the interior. Of course, many modern buildings are designed to make the most of natural light, but I don’t think I’ve seen anything that specifically lights up aspects of a modern building at particular times – it’s certainly not a common thing. Perhaps this is something that modern-day architecture could explore to provide additional interest in our buildings.
