Here's a little bit of information about the Estate from the Ashland Facebook Page:
Kentucky's first National Historic Landmark. 19th century architecture, 17 acres, formal garden and seasonal cafe. Dedicated to preserving the legacy of one of America's greatest statesmen, Henry Clay: The Great Compromiser. Open since 1950.
Visit the Ashland Website or Facebook Page for more information about hours, dates the estate is open, tour information, directions, and events. At a glance, it seems like there are many interesting events that happen at this grand estate. I could tell when we were there that not only tourists came to see Ashland, but that the neighborhood folks spent alot of time on the grounds as well...some were walking dogs, some playing with their kids, some taking pictures, and some just enjoying a leisurely walk on a beautiful day.
