Belgium’s tallest Gallo-Roman tumulus has had protected heritage status since 1971. It stands at 15 metres tall with a diameter of 52 metres and dates back to the 2nd century. It was probably the tomb of a rich landowner and was placed along an important Roman road. In the past, communal festivals would have been celebrated on the peak and some events still take place today at its foot. For example, Gallo-Roman Days are held there at the end of May and feature many activities including a gladiator combat performance.
