Lazaretto Quarantine Station

Tinicum Township, Delaware County, Pennsylvania

Marker Inscription

A rare surviving example of a quarantine station, the Lazaretto was the introduction to America for many immigrants. Established in 1799 in reaction to a yellow fever epidemic, it operated until 1893 to inspect cargo and passengers for infectious diseases. Affected cargo was fumigated or destroyed and ill passengers were hospitalized and quarantined until recovery or death. The cemetery was here and original structures remain nearby.

The Story

Established in 1799 after a devastating yellow fever epidemic, the Lazaretto stood as Philadelphia's line of defense against imported disease. For nearly a century, ships bound for the port stopped here first so that cargo could be inspected or fumigated and passengers examined; the sick were hospitalized and held until they recovered — or died. For countless arriving immigrants, this quarantine station was their very first taste of America.

Why it matters

One of the rare surviving quarantine stations in the country, the Lazaretto marks an early chapter in America's long effort to balance public health, commerce, and the welcome of newcomers.

Governor Printz Park

Tinicum Township, PA · est. 1948

On this low island in the Delaware, Swedish colonists founded New Sweden's foothold in 1643, the first permanent European settlement in what is now Pennsylvania. Here stood the Printzhof, the fortified residence and capitol of Governor Johan Printz, the imposing leader who governed the tiny colony. Though New Sweden was short-lived, this ground marks where organized European settlement in Pennsylvania began, decades before William Penn's arrival.

Tinicum

Tinicum Township, PA · est. 1947

In 1643 Colonel Johan Printz, the imposing governor of New Sweden, established his seat at Tinicum, founding what is recognized as the first permanent European settlement in present-day Pennsylvania. For a dozen years the Swedish colony held this ground along the Delaware, until the wider contest for the river swept it away — first to the Dutch in 1655, then to the English in 1664. Tinicum's brief Swedish chapter left a lasting mark on the region's earliest colonial identity.

Morton Homestead

Prospect Park, PA · est. 1966

This riverside homestead was begun around 1654 by Morton Mortonson, part of the Swedish and Finnish settlement of New Sweden along the Delaware, and it is among the oldest European-built structures in the region. The family line ran forward to John Morton, the Pennsylvania delegate who cast a decisive vote and signed the Declaration of Independence in 1776.

Morton Morton House

Norwood, PA · est. 2019

Long before there was a United States, Swedish colonists settled the lower Delaware Valley as part of New Sweden. This house, raised around 1750, was built by a great-grandson of that pioneer line — kin to John Morton, the Delaware County farmer whose vote helped carry Pennsylvania for independence in 1776. Its walls tie a quiet borough to the region's earliest European roots.
