Cistercian monks founded Tintern Abbey in the early 12th century. Tintern is located in South Wales, just a few miles from the border with England, which meant it was spared many of the Welsh uprisings that plagues other monastic communities of the middle ages. The monastery was destroyed during the dissolution of the monasteries under Henry VIII, being handed over in 1536. For some reason much of the church remains, not having been dismantled and used for building, like in other areas. Below you can see the ceiling-less crossing.
I was first in Wales three and a half years ago, but did not have time to get to Tintern. When I was back in Cardiff with my family I decided I would not miss my opportunity a second time. It has been nearly a month since I was in Tintern, so I have forgotten a great deal of the specific history, but I will try to caption the pictures well.
