Eilean Glas Lighthouse was one of the original four lights commissioned by the Commissioners of the Northern Lights, and the first in the Hebrides. These lighthouses were built by Thomas Smith. Eilean Glas light was first displayed in 1789. The original tower was replaced in 1824 by Smith's stepson Robert Stevenson. In 1852 the light was changed to a revolving system lens. The lighthouse was an early candidate for automation and this was carried out in 1978. Several of the original buildings have been sold off. The fog signal was discontinued in the 1980s although the horn remains place as a decoration.
The 30-metre tower is painted with two distinctive broad red bands. Light is now from catoptric sealed beam lamps, mounted on a gear less pedestal.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
