MARSHALLTOWN, Iowa (AP) — Residents gathered in downtown Marshalltown to cheer the return of the dome atop the tornado-damaged and time-ravaged Marshall County Courthouse. Streets around the courthouse were lined Tuesday with cheering people _ some shoulder to shoulder despite warnings about social distancing during the COVID-19 pandemic. The dome and building were damaged by a tornado that tore through Marshalltown on July 19, 2018, injuring several people. Falling debris broke three courthouse sprinkler lines, resulting in a flood of water entering the structure. The tornado damage exposed rot and wear and tear that needed repair. The building is more than 130 years old.
