it should be "Why Kellie's Castle was made" but nvm, we still learning :)
hope this would help you.
During construction, a virulent strain of Spanish Flu struck his workmen. When his workmen approached him to build a temple nearby, Smith readily agreed. In return for his generosity, they built a statue of him beside the other deities on the temple wall. It is believed that a tunnel was built to the temple from the castle.
Smith's mansion is accessible from the main road across a bridge over a stream. His house was so unique that it was even mentioned in the London Financier newspaper on 15 September 1911.
