Nearly 1,000 homes in Bath, England were evacuated late Thursday night, after an unexploded World War Two bomb was found under a local high school. 

Bomb disposal teams were dispatched to the Royal High School late Thursday to assess the situation, the Daily Mail reports. The find: a 500-pound bomb just feet below a now-defunct playground. 

A 300-foot exclusion zone was set up along Lansdown Road in the town as the Explosive Ordnance Disposal (EOD) workers did their work. A full 250 tons of sandbags surround the site. 

Meanwhile, evacuated families may not be allowed to return for 48 hours. 

This is not the first time a WWII bomb has surfaced to cause panic among modern-day residents. 

In May 2015, 20,000 residents of Cologne were evacuated after a 440-pound bomb was found and deactivated.
