Killyleagh in the context of Sir Hans Sloane

Sir Hans Sloane, 1st Baronet, FRS (16 April 1660 – 11 January 1753) was an Anglo-Irish physician, naturalist, and collector. He had a collection of 71,000 items which he bequeathed to the British nation, thus providing the foundation of the British Museum, the British Library, and the Natural History Museum, London.

Elected to the Royal Society at the age of 24, Sloane travelled to the Caribbean in 1687 and documented his travels and findings with extensive publications years later. Sloane was a renowned medical doctor among the aristocracy, and was elected to the Royal College of Physicians at age 27. Though he is credited with the invention of chocolate milk, it is more likely that he learned the practice of adding milk to drinking chocolate while living and working in Jamaica. Streets and places were later named after him, including Hans Place, Hans Crescent, and Sloane Square in and around Chelsea, London—the area of his final residence—and also Sir Hans Sloane Square in Killyleagh, his birthplace in Ulster.

Killyleagh Castle is a castle in the village of Killyleagh, County Down, Northern Ireland. It is believed to be one of the oldest inhabited castles in the country, with parts dating back to 1180. It follows the architectural style of a Loire Valley château, being redesigned by the architect Sir Charles Lanyon in the mid-19th century. It has been owned by the Hamilton family since the early 17th century.

It is currently the home of Gawn Rowan Hamilton and his young family. The castle hosts occasional concerts; performers have included Van Morrison, Glen Hansard and Bap Kennedy. The gate lodges provide self-catering holiday accommodation. From 2012 to 2014, the castle was used to film CBBC show Dani's Castle.

The A22 is a road in County Down, in Northern Ireland. Its route starts in Dundonald and runs to Comber, forming the main transport corridor connecting Belfast and Comber, a commuter town situated 8 miles outside of the city. After bypassing Comber town itself, the route continues along the eastern shores of, though not directly adjacent to, Strangford Lough. The route passes through Lisbane, Balloo (near Killinchy), and Killyleagh, terminating in Downpatrick.

Strangford Lough is a large sea lough or inlet in County Down, in the east of Northern Ireland. It is the largest inlet in Ireland and the wider British Isles, covering 150 km (58 sq mi). The lough is almost fully enclosed by the Ards Peninsula and is linked to the Irish Sea by a long narrow channel at its southeastern edge. The main body of the lough has at least seventy islands along with many islets (pladdies), bays, coves, headlands and mudflats. It is part of the Strangford and Lecale Area of Outstanding Natural Beauty. Strangford Lough was designated as Northern Ireland's first Marine Conservation Zone in 2013, and has been designated a Special Area of Conservation for its important wildlife.

Strangford Lough is a popular tourist destination noted for its fishing and scenery. Towns and villages around the lough include Killyleagh, Comber, Newtownards, Portaferry and Strangford. The latter two straddle either shore of the narrow Strangford channel, and are connected by a car ferry.
