Otmoor

Otmoor or Ot Moor is an area of wetland and wet grassland in Oxfordshire, England, located halfway between Oxford and Bicester. It is about 60 metres (200 ft) above sea level, and has an area of approximately 160 hectares (400 acres).

It is encircled by the "Seven Towns" of Otmoor: Beckley, Noke, Oddington, Charlton-on-Otmoor, Fencott, Murcott and Horton-cum-Studley.

Part of it is a nature reserve, RSPB Otmoor, which adjoins a Ministry of Defence firing range, which is part of a Site of Special Scientific Interest.

Bisected north–south by the Roman Road between Alchester and Dorchester-on-Thames, its name is derived from the Old English for "Otta's Fen".

Watered by the River Ray, it was until the early 19th century unenclosed marshland, and regularly flooded in winter. An Enclosure Act was passed in 1815, under which the area was extensively drained. This disadvantaged the local farmers and led to civil disturbances known as the Otmoor Riots of 1829–30.

In 1920 the Royal Air Force acquired Otmoor for use as a bombing range. Part of the moor remains in military use as a rifle range, and is also a large part of Otmoor Site of Special Scientific Interest (SSSI).
