Will your walls still be standing in 2000 years?

This is the remains 2nd largest Roman civil building in Britain, and it`s here in Leicester. The Jewry Wall is nearly 2000 years old and is part of the Roman baths which was excavated in 1936.
The large archways lead into a gym which is now underneath the mediaeval church of St. Nicholas..the gable end is just visible over the wall. The Romans would go to the gym for a workout, play some sport and then go through into the baths which where a series of hot & cold plunge pools...bit like a Fitness First.
The holes in the wall are where planks of wood where inserted to give support to the `brickies` as they laid layers of tile and then stone and mortar...the tiles levelling the layers off..this section is about 30ft high and 6ft thick..no mean feat.
It`s an odd contrast to have this Roman edifice within the grounds of a 1960`s concrete built college adjacent to a mediaeval church 300 yards away from a 21st century shopping mall. Which will still be standing for the next 2000 years?
