Columcille Megalith Park is located in eastern Pennsylvania a few miles north of Bangor, and is inspired by the Scottish island of Iona, where an Irish monk named Columba established a monastery. In Irish, his name was Colum Cille, from which the park gets its name. Columcille is privately owned, but open to the public. There is no admission charge, but the park has several places where donations may be left. Walking in from the small roadside parking area, I could see these stones and a circular tower.
A circle of standing stones surrounds a sitting boulder.
Here's a closer shot of the tower.
This trilithon is so big that you can walk through it.
A pathway leads downhill from the trilithon and past another group of stones.
This dolmen reminded me of the Poulnabrone Dolmen in Ireland.
This small pedestrian bridge is partially in shadow.
The Chapel of St. Columba may be used for gatherings, with prior permission from the park's owners, or for quiet meditation by individuals. Be sure to close the door on your way out.
Set on a small mound, this off-white stone has an interesting surface.
At the park's eastern end are these three large stones. I called them the "three monsters".
