The HHT was created to take you to places you probably have gone by many times without knowing it was part of Harford County’s history. At the end of this road and up the steps on the left is the Liriodendron. Established in 1835, Liriodendron Mansion is a historic home located on Gordon Street. The house was built by Dr. Howard Kelly, a respected surgeon and a founder-member of John Hopkins Medical College. Today, the home is used as a venue, playing host to private events such as weddings and parties.
