Hidden History
Lot Line Marker
Southeast corner of Peach and 8th
At the southeast corner of Peach and 8th, tucked flush into the sidewalk, sits a little metal secret: a Lot Line corner marker. Stamped with the words “Lot Line” and the exact degree of the boundary angle, it’s Erie’s way of whispering geometry into the street. These markers are the city’s hidden cartographers, quietly declaring where one property stops and another begins. Surveyors depend on them, builders trust them, and passersby rarely notice them—yet they’re the unsung punctuation marks of downtown, keeping Erie’s invisible lines neat, tidy, and just a bit mysterious.
