Inishowen man Adam Rory Porter has created a stunning timelapse of the Autumnal Equinox solar alignment at Grianan of Aileach in Burt.

Twice a year, at dawn, on the spring and autumnal equinoxes, something spectacular occurs at Grianan of Aileach.

The rising sun aligns with the monument and rays beam through the entrance, ‘splitting’ the structure in two.

Adam captured the autumn equinox of Sunday 21st September last on video and it’s an incredible sight.
