The Gingerbread Town
Downham
Market
“Gingerbread Town”
Take a look around Downham Market in
between the modern style brick buildings you will see a gingerbread looking stone
incorporated into the architecture, giving the town its nickname. This is Carrstone,
a rock that has been quarried locally and has been used for façades, structural and galeted architecture in the
town's buildings.
The rock that gives Downham Market’s
architecture its unique
character is Carrstone, a sandstone rock deposited
in the Cretaceous c.108 million years ago and found in through the East of
England but is at its thickest and outcroping in West Norfolk; with a maximum 18
metre thickness recorded in a borehole in Hunstanton, but more commonly its about 5 m thick, reducing inland. The most dramatic location to see Carrstone in-situ is in the
cliffs at Hunstanton where the Carrstone Formation is found at the bottom overlain by the Hunstanton Formation (Red Chalk) and Ferriby Chalk
Formation (White Chalk). It is Carrstone from an extension of the same bed seen in the cliffs
at Hunstanton that has been used in the architecture of Downham Market.
Carrstone gets its distinctive look of
gingerbread from the combination of fine to medium grains combined with oolites
and the iron oxide (rust) content of the matrix holding the grains. This gives
the distinctive granular crumbly look which when weathered is an orange-brown
colour and looks similar to freshly baked
gingerbread. The effect of weathering on the colour of Carrstone can been
throughout Downham Market’s buildings.
A really lovely town.
