A large section of the rear of Shenandoah’s J.W. Cooper High School collapsed Saturday, forcing the closing of two streets.

Borough officials closed Lloyd Street at White Street and Lehigh Street at Lloyd Street.

Dislodged bricks could be seen where they landed around the base of the building and a dislodged steel beam hangs diagonally from a gaping hole in the east side.

The failure of the building’s east wall also prompted the immediate relocation of the Beverly Mattson Memorial Food Bank as the borough condemned the structure.

The building is owned by Kent Steinmetz who’s been spearheading a drive to save the site since 2009.

When opened as Shenandoah High School in 1919, it reflected the dynamic growth of the town, boasting an impressive auditorium and balcony and indoor pool, the second oldest in Pennsylvania and oldest inside a school.

The building became an elementary school in 1981 and closed for good in 1994.

In the 1920s and ’30s, Shenandoah was the most densely populated place in the U.S. with 30,000 residents living within one square mile. The school, later named J.W. Cooper Memorial High School to honor the first principal, was built in the center of the town.
