Mountains, engineering and the Chelsea Flower Show are among many subjects to be explored in Keswick Lecture Society's 2017 programme.

Among the fortnightly talks, Chris Harling will talk about exploring the Tien Shan range in Kyrgyzstan, where he faced added problems while guiding clients who clearly did not have the experience that they claimed.

Local historian Roy Ellis will talk about the mass trespass in 1887 when 2000 people marched to the top of Latrigg. He will explore the background to the event, the ensuing court case and the role played by Canon Rawnsley.

Film producer Terry Abraham will present his photography and the stories behind the making of his BBC series Life on a Mountain.

In the fourth mountain-themed event of the series, Clive Hutchby will talk about how he is revising the whole series of Wainwright Guides, which were written more than 50 years ago.

Broadcaster and explorer Nick Crane, known for his BBC2 series of Coast, Great British Journey and Map Man and Town, will talk about the ancient relationship between people and place and the deep-rooted tensions between town and countryside in The Making of the British Landscape.

John Mather will talk about Sir Thomas Bouch, Cumbria’s forgotten engineering genius, who designed and constructed the Cockermouth, Keswick and Penrith Railway, but he was perhaps better known for the building of the Tay Rail Bridge which tragically collapsed in 1878.

Doug Stewart will give a behind-the-scenes account of the Chelsea Flower Show, while Keith Offord will talk about Aristocrats of the Air.

All lectures take place in The Queen’s Hall at Keswick School on Tuesday evenings.
