FERRICRETE

One of the few building stones native to East Anglia


Wivenhoe, Essex
 

Good building stone is rare in Essex and East Anglia but one exception is the rock ferricrete.
  
The movement of iron-rich groundwater in Ice Age gravels has resulted in the formation of hard, solid masses of ferricrete which is an ‘iron pan’ at the level of the water table. It is basically an iron-cemented gravel but it can be extremely hard and durable. 
  
Ferricrete has been used in the construction of several Essex churches.
