Brick making started in Bletchley in the early 1890's when a company called T.G. Reads started making handmade bricks. They were taken over by the London Brick Company in 1925. Bletchley Flettons opened at Skew Bridge in 1933 but was also taken over by the London Brick Company. Bletchley Flettons was renamed The Jubilee Works in 1950 and linked to the Bletchley works via a road called the Burma Road. The London Brick Company made Fletton bricks and at the height of production they were making five million bricks per week. The kilns were constantly burning and only stopped during the second world war when the Bletchley works was shut down and the kilns were used as ammunition stores. Many workers were from overseas, mainly Italians, Poles and Ukranians also German ex Prisoners of War. There is still a substantial Italian community in Bletchley to-day

Brickmaking remained a prominent industry in Bletchley until the closure of the brickworks in1990. The pits from where the clay was excavated were remodelled and now form a nature reserve called the Blue Lagoon with lakes, pathways, picnic areas and abundant wildlife.

Fletton Bricks

When a brickmaker in Peterborough discovered a deeper shaley clay called Oxford Blue a new method of brickmaking developed called the Fletton Process. The advantages of the lower Oxford clay belt is the uniformity of its formation. Also it did not need the addition of water to break it down, just heavy grinding. The natural moisture content and low plasticity also meant the unfired bricks were sufficiently strong enough to be stacked in a kiln straight away. Another unique advantage of the Oxford clay is its high carbon content which means once heated the bricks would virtually fire themselves. This method meant that more bricks could be produced more economically. The Oxford Clay belt, which dates back to the Jurassic period, runs from Yorkshire to Dorset taking in Bletchley along the way.
