Trees threaten Roman wall in St. Albans

Sycamore trees are the culprits in damage done to the historic Roman wall in St. Albans, England. Built in the 3rd century, the wall is what remains of a five metres high and three metres wide wall, circling the city, with a walkway on top. (photo)

Officials do not plan to remove the trees, which are a vital part of Verulamium Park, but seedlings which could damage the wall will be carefully removed. "The Roman wall has had trees growing over it since late Roman times, and has in fact been a wooded area for some 1600 years," explained Chris Green, the Museums and Heritage Officer at St Albans District Council.
