A Roman tile kiln 1 (CAG No. Kiln 36) situated north of the River Colne and to the east of Moat Farm, Lexden. The kiln was initially discovered during ploughing operations by the farmer Mr. Bruce Andrews. The kiln was one of two kilns of the rectangular up-draught type with sloping bottomed lateral flues. excavated over two seasons in 1969-70 (ECC697). The second kiln (MCC1795) was built within the first.

All that remained of the earliest kiln were the outer below-ground walls built of clay blocks. The internal structure and stoke-hole tunnel had been completely removed for the insertion of the later kiln. The stoke-hole pit was not excavated. Dating evidence for the kiln indicated the latter half of the 1st century AD.<1>
