Dinas Bran, Llangollen

From the first year geology field mapping training course this weekend. The remnants of Castell Dinas Bran, sitting atop Silurian siltstone. Taken from the Carboniferous Limestone escarpment.

Situated on the site of an Iron Age hillfort whose embankments can be seen on the slopes, the castle seen was probably built in the mid-1200’s and only occupied by the princes of Powys Fadog for a couple of decades before it was destroyed by fire in 1277 during the invasion by Edward I’s army.
