Until the late 18th century, Weybridge was as a very small village with a river crossing, seed milling to make flour and nurseries would continue to provide the major source of home-grown income until the 20th century but no tanneries, major coaching houses, shops, markets, forges or gunpowder works are documented for example in the medieval period. The earliest monuments on the tower wall of St James's Church are 15th-century plaques, and the Church was rebuilt in 1848 with a south aisle added in 1864. In 1537, the south-west of Walton on Thames extra-territorially a manor house affiliated to Weybridge on what was a border of Weybridge and Walton, Oatlands Palace, was built by Henry VIII, which was where he married his fifth wife Catherine Howard. When it was demolished in 1650, bricks from its walls helped to line the then-new Wey Navigation canal.
