"Refurbished in 2015, Thurso Library was built in 1862 as the Miller Institute and was later turned into the Thurso Library and Swanson Gallery and stands at the end of Sinclair land in Davidson’s Street. With its clock tower and pillared facade it makes for an imposing but welcoming building in Thurso." Source: https://www.highlifehighland.com/libraries/thurso-library

Some general info about the Millenium mileposts - found on https://www.sustrans.org.uk/national-cycle-network/millennium-mileposts: "Unveiled in the year 2000, they are a celebration of the freedom and diversity of the National Cycle Network. Over 1,000 Millennium Mileposts were installed, stretching to all corners of the UK, some as far north as the Shetland Islands. You’ll find them at scenic spots on the Network, such as coastal paths and nature reserves. They can also be found at train stations and other key locations where the Network runs through villages, towns and cities."

This is a pretty commercialised spot, but for a good reason. The end or start point of many a biking and hiking adventure. Ours took 12 days, south to north, and I was pretty glad to see this signpost.

A very beautiful old lighthouse. Unfortunately, it's not open to visitors as it's privately owned.

Sinclair, the eldest son of Sir John Sinclair, 1st Baronet of Ulbster, and Diana, only daughter of Alexander Macdonald, 1st Baron Macdonald, was born in Edinburgh. His siblings were John, William, and Catherine Sinclair. At ten, he entered Harrow School under Dr. Drury, where he studied with Lord Byron and Sir Robert Peel. Byron described Sinclair as "the prodigy of our school days. He made exercises for half the school (in the true sense of the word), verses at will, and subjects without them. He was a friend of mine, and as near to me." At sixteen, Sinclair left Harrow for Göttingen. He was arrested as a spy and brought before Napoleon, who interrogated him and ordered his release. In 1826, Sinclair published a privately printed account of the interview (Edinburgh, 1826, 8vo).
