Tualatin, OR

The 65th Meridian doesn't get near the recognition (or signage) of the famous 45th Parallel, but this monument helps to make up for it.

Keen-eyed Tualatin, Oregon has erected a monument to the 65th meridian (a longitude). This particular invisible line runs through the city, and even has an official name, the Principal Willamette Meridian. The county surveyor, interviewed by the Tualatin Times, declares that “the Willamette Meridian line is perfect in measurement.” Like the 45th parallel, the 65th meridian cuts through countless communities, but only Tualatin has marked it with a photo op, and now all on-the-grid fans will have to add it to their pilgrimage itineraries.
