The Franklin School is a building designed by Adolf Cluss in the German round-arch style, located on Franklin Square at 13th and K Street in Washington, D.C.
It was constructed in 1869 and initially served as a flagship school building.
It later took on various other educational roles, and became a homeless shelter in the 2000s.
In 2020, it became the location of the Planet Word museum after its interior was largely gutted.
