ROCKS matter, as Geology of London reminds us. The Romans found out as much when angry locals burnt down the city’s wooden defences in AD 60. At first it had seemed to make sense to site Londinium on dry sand close to the Thames, with good spring water to supply their bath houses. The lack of local solid rock, however, has created problems ever since – and not just for building fortifications.
Although this is a fairly technical memoir, Geology of London gives a fascinating and well-illustrated insight into what lies beneath the city and its suburbs.
Geological problems still bedevil…
