The Antonine Wall at Callender House is both impressive and a disappointment as it simulateously shows the size and scale of its construction in the turf ramparts that have survived, but also how modern architectural and societal needs can destroy heritage.
The ditch, wall and rampart of the Antonine Wall are clear to see in the gardens/parkland of Callendar House. Although well-preserved, construction of Falkirk's southern link road destroyed a good chunk of the Wall and the stone base was completely stripped over this distance. Then in the 1960s, five tower blocks at Seaton Place do not exactly add to the spirit of place.
