Blue Lias
A blueish-grey lime mudstone used quite widely in South Worcestershire. Few if any traces remain of the quarries which were presumably backfilled and now lie under agricultural land. Originally most building may have been rendered as The Lias generally weathers quite poorly when exposed. It is easily recognised by its pale blueish colour, thin tabular blocks and characteristic thin laminae of coarse and fine material. Fossils, mainly bivalves, are common. Examples of use include the Littletons, just north of Evesham, Croome Court’s follies and outbuildings and several walls and bridges in Worcester.
