Philadelphians will soon be able to learn about the Delaware River's rich, sometimes sordid, history via a 90-foot-tall holographic ship set to "dock" at the Race Street Pier.

The free, "three-dimensional light and water-based" installation will see an 18-century "Ghost Ship" projected underneath the Benjamin Franklin Bridge, the Delaware River Waterfront Corporation announced.

The installation, created by Romanian-based Biangle Studio, will explore the river's importance to Philadelphia and draws from the "nuanced and complex history of the Delaware River in the 1700s," including its role in the slave trade, according to the DRWC.

"Ghost Ship" will debut at Race Street Pier Oct. 4 and will be on display Wednesdays through Sundays from 7-10 p.m. through Nov. 3. The installation is curated by Ryan Strand Greenberg and will also be accompanied by self-guided audio tours.
