The Mount of Troy is one of Zeeland's most famous flying hills. It was once the home of the powerful lords of Borssele, a so-called motte castle. Together with the medieval village of Monster, the remains of this complex were drowned by the floods of 1530/1532.
To enhance the experiential value of the remaining mound, several non-destructive investigations were conducted in 2015. This was all in the context of the four-hundredth anniversary of the "new" Borssele, founded in 1616.
