Strategically Placed
After a while, Simon and his dad stopped digging and started researching. They looked up the plot number and saw that, before the previous owners, it had stood empty. Still, Gerald pointed out that this was a strategic place in town!
More Research
Simon claimed that his dad saw it first as an air-raid shelter. They Googled the information to find out there there were many in the area. In fact, it was built in World War II! The previous owner likely knew it was there and filled it in when he added the home.
