Tantallon Castle & Views of Bass Rock

Tantallon Castle is a semi-ruined mid-14th-century fortress, located 5 kilometres east of North Berwick, in East Lothian, Scotland. It sits atop a promontory opposite the Bass Rock, looking out onto the Firth of Forth. The last medieval curtain wall castle to be constructed in Scotland, Tantallon comprises a single wall blocking off the headland, with the other three sides naturally protected by sea cliffs.

Bass rock is a steep-sided volcanic rock, 107 metres (351 ft) at its highest point, and is home to a large colony of gannets. The rock is currently uninhabited, but historically has been settled by an early Christian hermit, and later was the site of an important castle, which after the Commonwealth period was used as a prison. The island plays host to more than 150,000 gannets and is the world's largest colony of Northern gannets. When viewed from the mainland, large regions of the surface appear white due to the sheer number of birds (and their droppings, which give off 152,000 kg of ammonia per year).
