Patterson Park is located in Baltimore MD. It began as six acres of land donated in 1827 and now comprises 137. The Park’s high ground was the site of a major battle in the War of 1812. An observatory in the form of a pagoda was built in 1891 and remains a major attraction. The Boat Lake was created when a military installation was removed in 1864, towards the end of the Civil War. The first photo shows Boat Lake in 1890. The third photo shows visitors on the Pagoda steps in 1893.
