Cylburn began as the private estate of Jesse Tyson, president of the Baltimore Chrome Works Company that became Allied Chemical and occupied the site of Exelon’s new headquarters on the Harbor today. At Cylburn, Tyson began building his mansion in 1863 as a summer home for himself and his mother. On Saturday, June 8, please join us and our hosts from Baltimore City Recreation and Parks to discover its Italianate design, stone from Tyson’s own Bare Hills quarry (in Baltimore County), and the interior of hardwood, grand fireplaces, and ornate plasterwork!
