Archaeological site Forum Hadriani in Leidschendam-Voorburg

You're standing in Voorburg, on the site of Forum Hadriani. You won't see any ruins, but right under your feet lies an entire Roman town. Arentsburg park sits largely on top of its remains. See if you can spot the memorial column put up here in 2000. And in the neighbourhood next door, the line of the old town wall is marked out in the street pattern.
