Dunglass Castle on the shore of the Clyde Estuary near Bowling to the west of Glasgow. Originally built in 1380 for the Barony of Colhouquon. By the 1700s it lay in ruins. In 1899, the house in the background was bought by the parents of the Glasgow Style artists Margaret and Frances MacDonald. The interior was later re-modelled by Margaret's husband, Charles Rennie MacKintosh.
The Henry Bell Monument in Helensburgh. Born in West Lothian in 1767, Bell became obsessed with the idea of using steam engines to power ships around 1800. While is early experiments were unsuccessful, he received enouragement from none other than Admiral Lord Nelson, who in 1803 told the Admiralty, "My Lords, if you do not adopt Mr Bell's scheme, other nations will, and in the end vex every vein of this empire. It will succeed ... and you should encourage Mr Bell.".
In 1808, Bell moved to Helensburgh and it was here he built his first successful steam-powered vessel, a paddlesteamer called Comet, in 1812 and used it to create Europe's first successful steam-powered passenger service running between Helensburgh, Glasgow and Greenock. In 1820, the Comet was shipwrecked near Oban, but was soon replaced by the PS Comet II.
In 1825, the Comet II sank after colliding with another ship, killing 62 of the 80 passengers. After this, Bell abandoned his interest in steam-powered nautical navigation and he died in Helensburgh just a few years later in 1830.
