One of the Hammond-Harwood House’s biggest annual events is coming up on June 4 and 5. The House sponsors the Secret Garden tour, which gives attendees a chance to visit gardens in Annapolis that are otherwise closed to the public. This year, the tour features gardens in the oldest section of colonial Annapolis, in the neighborhood of Revel, Shipwright, Market, Conduit, and Duke of Gloucester Streets. The highlight of the tour is the garden at the John Ridout House at 120 Duke of Gloucester Street, which will only be accessible to Hammond-Harwood House members. Visit the Secret Garden Tour website to learn more and to purchase tickets.
