Isle of Man - Douglas Head

Overlooking the town of Douglas is the Great Union Camera Obscura. Built as a tourist attraction in 1892, this is the only camera obscura in the world with eleven apertures. A metal tube is rotated between each of these, and the captured light mirrored down and through a series of lenses onto a circular and concave white tabletop, to produce a properly-oriented changing view of the immediate locale.

Clearly visible is the Douglas Head Lighthouse, built in 1857 by David and Thomas Stevenson, and rebuilt in 1892. The tower is 66 feet tall, and provides a light at an elevation of 105 feet. The light, one of five on the island, was automated in 1986.
