What is the Historical Society of Pennsylvania?
The Historical Society of Pennsylvania was started way back in 1824. Its main goal is to collect and protect important historical items. These items help us learn about the past, especially the history of Pennsylvania.
The society keeps a huge collection of historical materials. This includes about 600,000 printed items. They also have over 19 million handwritten papers and graphic images. These collections cover history from the 1600s, 1700s, and 1800s.
In recent years, the society has started programs for younger people. These "Young Friends" programs help kids and teens learn about history in fun ways.
The Society's Historic Building
The Historical Society of Pennsylvania is located in a special building. It stands on the corner of 13th and Locust Streets in Philadelphia. This spot used to be home to a large house called the Patterson Mansion.
General Robert Patterson owned the mansion. He was a general who fought in the Mexican–American War and the American Civil War. After he passed away in 1881, the Historical Society bought his mansion. They wanted it to be their permanent home.
The mansion was later taken down between 1905 and 1909. A new, strong building was built in its place. This new building was designed to be fireproof. It was officially opened in 1910. Today, the building is listed on Philadelphia's Register of Historical Places. This means it is an important historical landmark.
