Community Collaboration with Parkside Association of Philadelphia

Taking place on Saturday, August 22, Highmark Mann’s Milestone Mashup is a free, campus-wide community event celebrating pivotal moments in our nation’s history that happened right here in Philadelphia. Designed as a journey through time, the event will bring these eras to life through a full day of engaging, family-friendly programming and activities.

The Milestones:

Two hundred fifty years ago, the United States declared its independence in Philadelphia on July 4, 1776. One hundred years later, Philadelphia hosted the 1876 Centennial Exposition, welcoming 10 million visitors from around the globe to Fairmount Park for the first World’s Fair in the United States. Today, this area is known as the Centennial District and is home to Highmark Mann. In 1976, as the country celebrated its Bicentennial, Highmark Mann was founded in West Fairmount Park. In 2026, these milestones come together as we celebrate the nation’s Semiquincentennial alongside Highmark Mann’s 50th anniversary.
