Experience one of Marietta’s most remarkable ancient events! Join The Castle’s archaeologist, Wes Clarke, for a special Winter Solstice Watch at Sacra Via Park, where the setting sun aligns with the prehistoric earthworks known as Sacra Via.
Large prehistoric earthwork complexes, like the one found in Marietta, were designed in part to track the passage of the seasons through astronomical observations. During this program, Clarke will discuss the celestial alignments of Marietta’s mound structures and their significance to the region’s Native American builders.
📍 Location: Sacra Via Park, between Second and Third Streets, Marietta, Ohio

What to Know Before You Go
The Solstice Watch is weather-dependent, and sighting may vary based on conditions.
If conditions are favorable, the event will begin with a brief discussion and viewing at Sacra Via before moving to the Quadranaou mound.
In case of precipitation or poor visibility, commentary will be provided from the gazebo shelter at Sacra Via Park.
Use the Solstice Map to locate the observation points.
The Sacra Via site (blue dot) marks the main alignment viewed from between the ancient parallel walls.
