Here’s the part of the obituary describing his creation of the arboretum,
He began planting trees (between 4,500 and 5,000). He swapped seedlings with Chatsworth where he had earlier befriended the 10th Duke of Devonshire and catalogued his library. Inspired by Capability Brown’s work at Chatsworth, and Humphry Repton’s work at other great estates he had visited through Christie’s, Spowers drained the land and created hills, lakes and ponds. He built an amphitheatre, installed statues, follies, monuments and bridges.
What is perhaps less well known, is that the arboretum is built on the land that was Frommow’s Nursery, which was so important to the early development of Lightwater.
Major Spowers contribution to the beauty and amenities of Lightwater and Windlesham has been truly significant. We should be proud that such a man lived among us.
