St. Marys Church, Ardleigh, ARDLEIGH, Tendring District, TM05382955, General geological site

hide/show OS map  


Building containing stonework of geological interest.


Site description

Ardleigh church has a variety of colour from a diversity of local building materials in an attractive patchwork. The church has a medieval tower and south porch but most of the rest is nineteenth century. The finest craftsmanship is knapped flint flushwork, imported probably from Suffolk but there are numerous erratics, providing geological interest.

The erratic cobbles are no doubt from local fields or gravel pits and almost certainly come from the local Ardleigh Gravel, laid down by an ancestor of the Thames about 550,000 years ago. Particularly noticeable are the cobbles of ferricrete, a local iron-rich conglomerate of flint pebbles.
