The Marks Tey Brick Works was established by John Wagstaffe, a farmer and brickmaker, in 1863. William Holman Collier, a young brickmaker from Reading, took over the brickworks by 1879. A claypit, known as the `Blue Hole' because of the colour of the clay when first dug, is adjacent to the works. Although the process is now mechanised, the bricks are still handmade and the complex retains buildings, structure as and equipment that relate to the history and development of the brickworks. The two circular brick kilns are designated as a Scheduled Monument (NHLE. No. 1020999); the western kiln is a Listed Building Grade II (NHLE on. 1266780). The complex was adopted onto the Local List by the Local Plan Committee on 24/08/20. A surviving and locally significant industrial complex that retains many historic features relating to the use and development of the brickworks, including various buildings, hand-drawn wagons and wagon tracks, equipment and brick pits.
