Middridge is one of the old green villages of County Durham probably dating from before Saxon times. It was mentioned in the Boldon book, the great survey of Bishop Hugh de Pudsey compiled in 1183. The basic shape of the village with two rows of houses facing on to the green certainly dates back to before the enclosures in the 1630s, although few of the older houses survive.

There is an old tradition of the Middridge Fairies who were said to live on a hill on the outskirts of the village. It was said that a lad named Willie once taunted the fairies who became angy and chased him all the way home to his house at Middridge Grange. The fairy Oberon threw his iron spear at the lad but he just got indoors in time and the spear stuck in the oak door. In the 1970s it was still possible to see the door with the split said to result from the spear thrust.

Middridge Grange is also renowned as the home of Captain Robert Byerley who in 1690 owned the Byerley Turk, the famous arab stallion from which all present thoroughbred racehorses are reputed to descend.

Coal was first mined in Middridge in Eden pit in 1872 and in the village itself at Charles pit in 1874. This pit was worked until the start of the first world war in 1914. The head workings and the mine tip were not cleared until the early 1970s when the village was redeveloped jointly by Shildon Town Council and the Aycliffe Development Corporation.

Principal buildings are the Bay Horse public house and the Village Hall which is situated at the east end of the village green. The Village Hall was originally built as a church school 1817 which was then closed in 1957. It was then used as a village hall, mainly by the Women's Institute until it was purchased by the Aycliffe Development Corporation in 1971 and immediately closed. In 1973 the Middridge Village Association was formed and raised funds to purchase and restore the hall which was reopened in 1978.
