Happy 190th Birthday Patterson Park! April 19, 1827 was the date William Patterson made his initial gift of six acres of land to become Patterson Park a in Baltimore City. To celebrate, we had a little birthday celebration with some of our members, with a sneak peek at our new case of artifacts from the Patterson Park 2014 archeological dig led by Baltimore Heritage. The case makes its public debut this season inside the base of the Pagoda. The Pagoda is open 12-6 p.m. every Sunday until mid-October, weather permitting, and the case will be on display whenever the Pagoda is open.
