Its the winter solstice coming up on the morning of the 21st. Solstice – sun stands still. Good way of putting it as it pauses before swinging back along the horizon towards its other point in summer. People are looking to sit in passage tombs (the properly aligned ones to be fair to them) and have the sun enter at sunrise. Cant do it. Don’t have the yearning for that mystic experience. If I want to be in a bunch of people huddled together waiting for the light to come in I can take a lift. I am interested in the people who built them though. I intend to get a compass point for sunrise on the horizon and use sticks and string to trace its shadow track. Plotting orthostats, galleries, etc. will be easy to visualise after that. Walking through it may give me some insights into the building of these truly interesting megalithic monuments. Did they possibly get construction quotes or permission perhaps? Were they built with a predetermined time in mind? How many people and how long? What did it look like as it progressed? Did they include parking? How would it be built? Fun aside it is interesting and may lead somewhere.
