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 historic city of Trogir is situated on a small island between the Croatian mainland and the island of Čiovo. Since 1997, it has been included in the UNESCO list of World Heritage Sites for its Venetian architecture.
Trogir has 2300 years of continuous urban tradition. Its culture was created under the influence of the ancient Greeks, and then the Romans, and Venetians. Trogir has a high concentration of palaces, churches, and towers, as well as a fortress on a small island. The orthogonal street plan of this island settlement dates back to the Hellenistic period and it was embellished by successive rulers with many fine public and domestic buildings and fortifications. Its beautiful Romanesque churches are complemented by the outstanding Renaissance and Baroque buildings from the Venetian period.
Trogir is the best-preserved Romanesque-Gothic complex not only in the Adriatic, but in all of Central Europe. Trogir's medieval core, surrounded by walls, comprises a preserved castle and tower and a series of dwellings and palaces from the Romanesque, Gothic, Renaissance and Baroque periods. Trogir's grandest building is the church of St. Lawrence, whose main west portal is a masterpiece by Radovan, and the most significant work of the Romanesque-Gothic style in Croatia.
