Via: Jarid Boosters: In the late 19th and early 20th centuries architecture was shifting dramatically. Fueled by the Industrial Age, the ancient brick and masonry structures of Old World origins were systematically replaced with cold, modern steel. However, more often than not, the entire city itself was renovated, revealing numerous unexpected findings during these excavations.
In Pittsburgh, Pennsylvania we have an event seen as the final removal of the massive “Grant’s Mound”, a historically significant “hill” which played a key role in the founding of Pittsburgh. Grant’s Mound, and the street level surrounding its ancient buildings, was lowered by a total of 33 feet, beginning with the “First Cut” in 1836, and concluding with the “Final Cut” of 1912 and 1913, which is the focus of our photographic evidence today.
These images showcase numerous anomalies that only became visible due to the excavations, with the most unexplainable being dozens of structures with foundations running 30 feet (or more) below the original surface of the mound. Even stranger, upon excavations these once-buried levels sometimes contained things like windows, doorways to the outside, ornate brickwork, and even statues – appearing to indicate that these “foundation” layers were not always meant to be underground.
