This paper investigates the land- and sky-scapes surrounding the dolmens of Costa da Morte (Coast of Death), Galicia. Having uncovered previously that the location of megalithic monuments in this coherent area of the south-eastern side of the European Atlantic Façade connects to complex topographical features, we now show how this chosen topography connects to astronomical phenomena. We will see how the detailed shape of the horizon coincides with specific risings and settings of the Sun and Moon, providing further support for the notion that the creators of these monuments selectively drew upon a variety of features found in their natural world.
