Looking across the slate which forms part of the coastline at Dunstanbrugh Castle in Alnwick. The castle was built by Earl Thomas of Lancaster in 1313, but unfortunately he failed to reach it when his rebellion was defeated, and he was subsequently executed in 1322. Thereafter the castle passed to John of Gaunt, who strengthened it against the Scots by converting the great twin towered gatehouse into a keep. The focus of fierce fighting during the Wars of the Roses, it was twice besieged and captured by Yorkist forces, but subsequently fell into decay. [source: English Heritage]
Taken a view from a very low angle, watching the sand blow across the rocks as the morning wind rises, we can follow the natural creases and lines filled with sand towards the castle. As the eye moves through the image to the castle and colours from the sunrise, you can notice the crystallised salt standing out white against the dark slate.
