Built in honor of Ireland's patron saint, Saint Patrick's Cathedral is adjacent to the famous well where tradition has it Saint Patrick baptised converts on his visit to Dublin. The massive and gorgeous cathedral was built in 1220!
This image is timeless to me. Although I took it in 2013, it looks like it could be from the 1940's.
Newgrange is an ancient temple constructed over 5,000 years ago (about 3,200 B.C.). It is older than Stonehenge in England and approximately 500 years older than the Great Pyramid of Giza in Egypt. It is located in the Boyne Valley and has been designated as a World Heritage Site by UNESCO. Newgrange is known for the almost magical illumination of its passage and chamber by the winter solstice sun. This is a remarkable achievment considering the time when it was built.
