At one time, the village of Congham had three churches which apparently stood in a straight line. Only St Andrew's Church survives. At the time of the Domesday book, Congham was larger in size than King's Lynn and Fakenham. St Andrew's Church has a 14th century tower. There was originally a side chapel built by the Spelman family but it was demolished in 1898. The font bowl is made of Purbeck marble and dates to the 13th century. The reredos and pulpit were produced by the Sandringham Estate carving workshop during the 1890s as part of an initiative to support the poor local villages. Beautiful kneelers adorn the pews. A memorial to Elsden Peter Harvey Everard records that he 'was accidentally knocked down by a locomotive' in 1860.
