Heraldic visitations were tours of inspection undertaken by Kings of Arms (or alternatively by heralds, or junior officers of arms, acting as their deputies) throughout England, Wales and Ireland. Their purpose was to register and regulate the coats of arms of nobility, gentry and boroughs, and to record pedigrees. They took place from 1530 to 1688, and their records (akin to an upper class census) provide important source material for historians and genealogists.
