Midgham is small, scattered village which extends from the Kennet & Avon canal and the Bath Road north into rolling Berkshire farmland and woods in the south of the Berksire Downs. It comprises a few mainly 20th century houses, a church and Midgham Park,  which has a double 15th-century Grade II listed red-brick former stable block with later additions and is at the top of a landscaped private park.

Scattered around the outskirts of the village are a few larger and older houses.

The church, St. Matthew's, was built in a 13th century style in 1869. The tower has an embattled parapet and an octagonal stone spire. Midgham had its own chapel from at least 1309. The Chapel of St. Margaret stood a little to the north-east of the present church, nearer Midgham House.

Midgham House was a large manor house in Midgham Park which was demolished in 1967 and eventually replaced by a smaller quasi-Rococo style house with Gothic windows in 1971.

A little south of the Bath Road is the London to Exeter railway line and the Kennet and Avon Canal. Midgham station is at nearby Woolhampton.

Midgham is just north of the Bath Road (A4) 2 miles east of Thatcham.
