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:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
