Although the "American Chestnut" tree is an endangered species because of a blight that kills the tree, there are a few survivors in Nova Scotia. The biggest one in Canada (Circumference) is in Hants County and is known as the Ashdale tree. The Uniacke House Museum which is run by the province of Nova Scotia has a very tall one on the Hot House Loop trial, with good signage to help you find it. There is also one in the City of Halifax Public Gardens. Click on the image to see the gallery.
