Thanks for visiting and great post - we're volunteers who run a web site about this place at www.kinneil.org ... when we meet or hear from visitors it's always remarkable how much less known Kinneil is relative to some other places given its historical significance. What took place at the Watt Cottage alone later went on to transform the world, and it's thought to be the only surviving building in Scotland with such a direct link to the life and work of one of the most globally-recognised and ingenious Scots in history. Hope you're able to return on a Saturday during the summer season to see inside the house and its unique 16th-Century wall paintings. Meanwhile the good little museum which you did visit is open free, daily except Tuesdays, 12.30-4pm – glad you found the staff member on duty helpful.
