Newgrange

We took a day trip out to the Irish countryside to see the famous Neolithic passage tombs. They're approximately 5000 years old, making them some of the oldest known monuments in the world. The builders of these tombs worshipped the sun and they frequently oriented the passages and openings to interact with sunlight on important days of the solar year. Newgrange is the most famous due to its size and the precise way in which sunlight enters its passage on the dawn of the winter solstice.

We arrived too late to go inside the tombs, so instead we spent a couple of hours walking through the beautiful countryside surrounding them. The weather was bizarre: we had pure sun, sun with snow, sun with rain, clouds with snow, clouds with rain, and back to sunshine...all in the span of three hours.
