The Caves of Nerja (Spanish: Cueva de Nerja) are a series of caverns close to the town of Nerja in the Province of Málaga, Spain. Stretching for almost 5 kilometres (3.1 mi), the caverns are one of Spain's major tourist attractions. Concerts are regularly held in one of the chambers, which forms a natural amphitheatre. The caves were re-discovered in modern times on 12 January 1959 by five friends, who entered through a narrow sinkhole known as "La Mina". This forms one of the two natural entrances to the cave system. A third entrance was created in 1960 to allow easy access for tourists, just south of the Sierras of Tejeda, Almijara and Alhama Natural Park. The cave is divided into two main parts known as Nerja I and Nerja II. Nerja I includes the Show Galleries which are open to the public, with relatively easy access via a flight of stairs and concreted pathways to allow tourists to move about in the cavern without difficulty. Nerja II, which is not open to the public, comprises the Upper Gallery discovered in 1960 and the New Gallery discovered in 1969.

Skara Brae /ˈskærə ˈbreɪ/ is a stone-built Neolithic settlement, located on the Bay of Skaill on the west coast of Mainland, the largest island in the Orkney archipelago of Scotland.

Skara Brae gained UNESCO World Heritage Site status as one of four sites making up "The Heart of Neolithic Orkney".a Older than Stonehenge and the Great Pyramids, it has been called the "Scottish Pompeii" because of its excellent preservation.
