Image of Cairn T (Passage Grave) by CianMcLiam

This might need an explanation as to what you are looking at! The photo was taken from the passage, the two green stones at the side are part of the passage, the stone at the bottom is the sill stone into the chamber. Between these stones is the central chamber with the rear chamber and ‘equinox stone’ dead ahead. The corbelling of the roof is also visible and the light inside the chamber is natural light from the entrance and the grid in the roof (its a 30 second exposure). There’s a bit of flash on the passage stones on each side to make up for me blocking the light coming in.
