Richard Rigby enlarged the quay around 1770 and tried to turn Mistley into a fashionable spa, commissioning Robert Adam around 1776; the scheme failed, but the twin Mistley Towers, all that remains of Adam's church after the body was demolished in 1870, still stand in the middle of the village.
Mistley is still a working quay on the Stour with maltings and warehousing alongside it, so the village mixes commercial port activity with tourism in a way that is unusual for its size.
The Mistley swans on the Walls are a genuine local landmark and the reason a large part of the village's visitor trade, pubs, the Thorn Hotel, cafes and antique shops, exists at all.
Mistley had a recorded population of about 2,956 at the 2021 census.
